Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The Consolidated Financial Statements include the accounts of LCI Industries and its wholly-owned subsidiaries ("LCII" and collectively with its subsidiaries, the "Company," "we," "us," or "our"). LCII has no unconsolidated subsidiaries. LCII, through its wholly-owned subsidiary, Lippert Components, Inc. and its subsidiaries (collectively, "Lippert Components," "LCI," or "Lippert"), supplies, domestically and internationally, a broad array of engineered components for the leading original equipment manufacturers ("OEMs") in the recreation and transportation product markets, consisting primarily of recreational vehicles ("RVs") and adjacent industries including boats; buses; trailers used to haul boats, livestock, equipment, and other cargo; trucks; trains; manufactured homes; and modular housing. The Company also supplies engineered components to the related aftermarkets of these industries, primarily by selling to retail dealers, wholesale distributors, and service centers, as well as direct to retail customers via the Internet. At December 31, 2022, the Company operated over 130 manufacturing and distribution facilities located throughout North America and Europe. Most industries where the Company sells products or where its products are used historically have been seasonal and are generally at the highest levels when the weather is moderate. Accordingly, the Company's sales and profits have generally been the highest in the second quarter and lowest in the fourth quarter. However, current and future seasonal industry trends have been, and may in the future be, different than in prior years due to various factors, including fluctuations in dealer inventories and the timing of dealer orders, the impact of international, national, and regional economic conditions and consumer confidence on retail sales of RVs and other products for which the Company sells its components, the impact of severe weather conditions on the timing of industry-wide shipments from time to time, as well as the coronavirus ("COVID-19") pandemic and related impacts. Additionally, many of the optional upgrades and non-critical replacements for RVs are purchased outside the normal product selling season, thereby causing certain Aftermarket Segment sales to be counter-seasonal, but this has been, and may in the future be, different as a result of the COVID-19 pandemic and the continuing impact of market and supply chain disruptions. The Company is not aware of any significant events which occurred subsequent to the balance sheet date but prior to the filing of this report that would have a material impact on the Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated. Certain prior year balances have been reclassified to conform to the current year presentation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to product returns, sales and purchase rebates, accounts receivable, inventories, goodwill and other intangible assets, net assets of acquired businesses, income taxes, warranty and product recall obligations, self-insurance obligations, operating lease right-of-use assets and obligations, asset retirement obligations, long-lived assets, pension and post-retirement benefits, stock-based compensation, segment allocations, contingent consideration, environmental liabilities, contingencies, and litigation. The Company bases its estimates on historical experience, other available information, and various other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other resources. Actual results and events could differ significantly from management estimates. Risks and Uncertainties The COVID-19 pandemic and the conflict between Russia and Ukraine (the "Russia-Ukraine War") have caused significant uncertainty and disruption in the global economy and financial markets. Management continues to closely monitor the impact of COVID-19 and the Russia-Ukraine War, as well as heightened tensions between China and Taiwan, on all aspects of the business. The extent to which COVID-19, the Russia-Ukraine War, and/or relations between China and Taiwan may impact the Company's liquidity, financial condition, and results of operations in the future remains uncertain.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. Accounts Receivable Accounts receivable are stated at historical carrying value, net of write-offs and allowances. The Company establishes allowances based upon historical experience, current conditions, and reasonable forecasts. Uncollectible accounts receivable are written off when a settlement is reached or when the Company has determined the balance will not be collected. Inventories Inventories are stated at the lower of cost (using the first-in, first-out (FIFO) method) or net realizable value. Cost includes material, labor, and overhead. Fixed Assets Fixed assets which are owned are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over the estimated useful lives of the properties and equipment. Leasehold improvements and leased equipment are amortized over the shorter of the lives of the leases or the underlying assets. Maintenance and repair costs that do not improve service potential or extend economic life are expensed as incurred. Leases The Company leases certain manufacturing and distribution facilities, administrative office space, semi-tractors, trailers, forklifts, and other equipment through operating leases with unrelated third parties. At contract inception, the Company determines whether a contract is or contains a lease and whether the lease should be classified as an operating or finance lease. The Company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments over the lease term at the commencement date. The Company uses its incremental borrowing rate based on information available at lease inception in determining the present value of the lease payments. The Company applies a portfolio approach for determining the incremental borrowing rate based on applicable lease terms and the current economic environment. Many of the Company's leases include renewal options, which are included in the lease term when it is reasonably certain the option will be exercised. Leases with an initial term of 12 months or less are recognized in lease expense on a straight-line basis over the lease term and not recorded on the Consolidated Balance Sheets. Certain of the Company's lease arrangements contain lease components (such as minimum rent payments) and non-lease components (such as common-area or other maintenance costs and taxes). The Company generally accounts for each component separately based on the estimated standalone price of each component. Some of the Company's lease arrangements include rental payments that are adjusted periodically for an index rate. These leases are initially measured using the projected payments in effect at the inception of the lease. Certain of the Company's leased semi-tractors, trailers, and forklifts include variable costs for usage or mileage. Such variable costs are expensed as incurred and included in variable lease costs. Finance leases and lease arrangements under which the Company is the lessor are not material to the Company's consolidated financial statements. The Company's lease agreements typically do not contain any significant residual value guarantees or restrictive covenants. Warranty The Company provides warranty terms based upon the type of product sold. The Company estimates the warranty accrual based upon various factors, including historical warranty costs, warranty claim lag, and sales. The accounting for warranty accruals requires the Company to make assumptions and judgments, and to the extent actual results differ from original estimates, adjustments to recorded accruals may be required. See Note 7 - Accrued Expenses and Other Current Liabilities for further detail. Income Taxes Deferred tax assets and liabilities are determined based on the temporary differences between the financial reporting and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all the deferred tax assets will not be realized. The Company accounts for uncertainty in tax positions by recognizing in its financial statements the impact of a tax position only if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Further, the Company assesses the tax benefits of the tax positions in its financial statements based on experience with similar tax positions, information obtained during the examination process and the advice of experts. The Company recognizes previously unrecognized tax benefits upon the earlier of the expiration of the period to assess tax in the applicable taxing jurisdiction or when the matter is constructively settled and upon changes in statutes or regulations and new case law or rulings. The Company classifies interest and penalties related to income taxes as a component of income tax expense in its Consolidated Statements of Income. Goodwill Goodwill represents the excess of the total consideration given in an acquisition of a business over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested at the reporting unit level for impairment annually in November, or more frequently if certain circumstances indicate a possible impairment may exist. In 2022 and 2021, the Company assessed qualitative factors of its reporting units to determine whether it was more likely than not the fair value of the reporting unit was less than its carrying amount, including goodwill. The qualitative impairment test consists of an assessment of qualitative factors, including general economic and industry conditions, market share, and input costs. Other Intangible Assets Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment. Intangible assets are amortized using either an accelerated or straight-line method, whichever best reflects the pattern in which the estimated future economic benefits of the asset will be consumed. The useful lives of intangible assets are determined after considering the expected cash flows and other specific facts and circumstances related to each intangible asset. Intangible assets with indefinite lives are not amortized, but instead are tested for impairment annually in November, or more frequently if certain circumstances indicate a possible impairment may exist. Impairment of Long-Lived Assets Long-lived assets, other than goodwill, are tested for impairment when changes in circumstances indicate their carrying value may not be recoverable. A determination of impairment, if any, is made based on the undiscounted value of estimated future cash flows, salvage value or expected net sales proceeds, depending on the circumstances. Impairment is measured as the excess of the carrying value over the estimated fair value of such assets. Foreign Currency Translation The financial statements of the Company's international subsidiaries generally are measured using the local currency as the functional currency. The translation from the applicable foreign currency to U.S. Dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using the weighted average exchange rate for the period. The resulting translation adjustments are recorded in accumulated other comprehensive income as a component of stockholders' equity. The Company reflects net foreign exchange transaction gains and losses resulting from the conversion of the transaction currency to functional currency as a component of foreign currency exchange gains or losses in selling, general and administrative expenses in the Consolidated Statements of Income. Stock-Based Compensation All stock-based compensation awards are expensed over their vesting period, based on fair value. For awards having a service-only vesting condition, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service periods. For awards with a performance vesting condition, which are subject to certain pre-established performance targets, the Company recognizes stock-based compensation expense on a graded-vesting basis to the extent it is probable the performance targets will be met. The fair values of deferred stock units, restricted stock units, restricted stock, and stock awards are based on the market price of the Company's common stock, all on the date the stock-based awards are granted. Revenue Recognition The Company recognizes revenue when performance obligations under the terms of contracts with customers are satisfied, which occurs with the transfer of control of the Company’s products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring its products to its customers. Sales, value added, and other taxes collected concurrent with revenue-producing activities are excluded from revenue. For the vast majority of product sales, the Company transfers control and recognizes revenue when it ships the product from its facility to its customer. The amount of consideration the Company receives, and the revenue recognized varies with sales discounts, volume rebate programs, and indexed material pricing. When the Company offers customers retrospective volume rebates, it estimates the expected rebates based on an analysis of historical experience. The Company adjusts its estimate of revenue related to volume rebates at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. Volume rebates are generally settled on a quarterly basis. When the Company offers customers prompt pay sales discounts or agrees to variable pricing based on material indices, it estimates the expected discounts or pricing adjustments based on an analysis of historical experience. The Company adjusts its estimate of revenue related to sales discounts and indexed material pricing to the expected value of the consideration to which the Company will be entitled. The Company includes the variable consideration in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur when the volume, discount or indexed material price uncertainties are resolved. See Note 15 - Segment Reporting for the Company's disclosures of disaggregated revenue. Shipping and Handling Costs The Company recognizes shipping and handling costs as fulfillment costs when control over products has transferred to the customer, and records the expense within selling, general and administrative expenses. Such costs aggregated $230.4 million, $203.8 million, and $104.4 million in the years ended December 31, 2022, 2021, and 2020, respectively. Legal Costs The Company expenses all legal costs associated with litigation as incurred. Legal expenses are included in selling, general and administrative expenses in the Consolidated Statements of Income. Fair Value Measurements Fair value is determined using a hierarchy that has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs. Recent Accounting Pronouncements There are no recent accounting pronouncements that have been issued and not yet adopted that are expected to have a material impact on our Consolidated Financial Statements.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE The following reconciliation details the denominator used in the computation of basic and diluted earnings per share for the years ended December 31: (In thousands) 2022 2021 2020 Weighted average shares outstanding for basic earnings per share 25,372 25,257 25,134 Common stock equivalents pertaining to stock-based awards 142 170 121 Weighted average shares outstanding for diluted earnings per share 25,514 25,427 25,255 Equity instruments excluded from diluted net earnings per share calculation as the effect would have been anti-dilutive 102 119 111 For the Company's 1.125 percent convertible senior notes due 2026 (the "Convertible Notes") issued in May 2021, the dilutive effect is calculated using the if-converted method. The Company is required, pursuant to the indenture governing the Convertible Notes, dated May 13, 2021, by and between the Company and U.S. Bank National Association, as trustee (the "Indenture"), to settle the principal amount of the Convertible Notes in cash and may elect to settle the remaining conversion obligation (i.e., the stock price in excess of the conversion price) in cash, shares of the Company's common stock, or a combination thereof. Under the if-converted method, the Company includes the number of shares required to satisfy the conversion obligation, assuming all the Convertible Notes are converted. The average closing price of the Company's common stock for the year ended December 31, 2022 is used as the basis for determining the dilutive effect on earnings per share. The average price of the Company's common stock for the year ended December 31, 2022 was less than the conversion price of $165.65, and, therefore, all associated shares were antidilutive. In conjunction with the issuance of the Convertible Notes, the Company, in privately negotiated transactions with certain commercial banks ("the Counterparties"), sold warrants to purchase 2.8 million shares of the Company's common stock (the "Warrants"). The Warrants have a strike price of $259.84 per share, subject to customary anti-dilution adjustments. For calculating the dilutive effect of the Warrants, the Company uses the treasury stock method. With this method, the Company assumes exercise of the Warrants at the beginning of the period, or at time of issuance if later, and issuance of shares of common stock upon exercise. Proceeds from the exercise of the Warrants are assumed to be used to repurchase shares of the Company's common stock at the average market price during the period. The incremental shares, representing the number of shares assumed to be received upon the exercise of the Warrants less the number of shares repurchased, are included in diluted shares. For periods where the Warrants' strike price of $259.84 per share is greater than the average share price of the Company's common stock for the period, the Warrants would be antidilutive. For the year ended December 31, 2022, the average share price was below the Warrant strike price, and therefore 2.8 million shares were considered antidilutive. In connection with the issuance of the Convertible Notes, the Company entered into privately negotiated call option contracts on the Company's common stock (the "Convertible Note Hedge Transactions") with the Counterparties. The Company paid an aggregate amount of $100.1 million to the Counterparties pursuant to the Convertible Note Hedge Transactions. The Convertible Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those in the Convertible Notes, approximately 2.8 million shares of the Company's common stock, the same number of shares initially underlying the Convertible Notes, at a strike price of approximately $165.65, subject to customary anti-dilution adjustments. The Convertible Note Hedge Transactions will expire upon the maturity of the Convertible Notes, subject to earlier exercise or termination. Exercise of the Convertible Note Hedge Transactions would reduce the number of shares of the Company's common stock outstanding, and therefore would be antidilutive.

Acquisitions, Goodwill and Other Intangible Assets	ACQUISITIONS, GOODWILL AND OTHER INTANGIBLE ASSETS Acquisitions in 2022 Way In November 2022, the Company acquired substantially all of the business assets of Way Interglobal Network LLC ("Way"), a distributor of innovative appliances and electronics to OEMs in the RV industry. The purchase price was $54.8 million, which includes a holdback payment of 2.0 million due on the first anniversary of the acquisition in November 2023. The holdback payment is recorded in the Consolidated Balance Sheet in accrued expenses and other current liabilities at December 31, 2022. The results of the acquired business have been included in the Consolidated Statements of Income since the acquisition date, primarily in the Company's OEM Segment. As the operations of this acquisition are not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented. The Company is in the process of determining the fair value of the assets acquired and liabilities assumed for the opening balance sheet, including net working capital, deferred taxes, and the fair value of intangible assets. The current estimates for intangible assets are based on a preliminary valuation and these estimates are subject to change when the valuation is finalized within the measurement period (not to exceed 12 months from the acquisition date). The acquisition of this business was preliminarily recorded as of the acquisition date as follows (in thousands) : Cash consideration $ 52,761 Fixed deferred consideration 2,000 Total fair value of consideration given $ 54,761 Identifiable intangible assets $ 13,000 Other assets acquired and liabilities assumed, net 36,783 Total fair value of net assets acquired $ 49,783 Goodwill (tax deductible) $ 4,978 The consideration given was greater than the fair value of the net assets acquired, resulting in goodwill. Girard In March 2022, the Company acquired substantially all of the business assets of Girard Systems and Girard Products LLC (collectively "Girard"), a manufacturer and distributor of proprietary awnings and tankless water heaters for OEMs and aftermarket customers in the RV, specialty vehicle, and related industries. The total fair value of consideration was approximately $70.7 million. The Company paid $50.0 million in cash consideration at closing, with fixed deferred consideration of $20.0 million paid in July 2022 and $0.7 million paid to true up net working capital in September 2022. The results of the acquired business have been included in the Consolidated Statements of Income since the acquisition date, in both the Company's OEM and Aftermarket Segments. As the operations of this acquisition are not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented. The acquisition of this business was recorded as of the acquisition date as follows (in thousands) : Cash consideration $ 50,664 Fixed deferred consideration 20,000 Total fair value of consideration given $ 70,664 Customer relationships $ 35,700 Identifiable intangible assets 7,820 Other assets acquired and liabilities assumed, net 14,442 Total fair value of net assets acquired $ 57,962 Goodwill (tax deductible) $ 12,702 The customer relationships intangible asset is being amortized over its estimated useful life of 20 years. The consideration given was greater than the fair value of the net assets acquired, resulting in goodwill. Other Acquisitions in 2022 During the twelve months ended December 31, 2022, the Company completed two other acquisitions for $5.0 million of cash purchase consideration. The preliminary purchase price allocations resulted in $0.8 million of goodwill (tax deductible). As these acquisitions are not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented. Acquisitions in 2021 Exertis In October 2021, the Company acquired certain business assets of Stampede Presentation Products, Inc. d/b/a Exertis ("Exertis"), a global distribution company, in exchange for $39.7 million. The acquisition qualifies as a business combination for accounting purposes and supports the acquisition of Furrion Holdings Limited ("Furrion") by allowing the Company to provide logistics and warehousing to serve Furrion's North American customer base. The results of the acquired business have been included in the Consolidated Statements of Income since the acquisition date, primarily in the Company's OEM Segment. As the operations of this acquisition are not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented. The Company had a pre-existing relationship with Exertis where Exertis had a prepaid asset and the Company had an equal and offsetting deferred revenue liability of $24.8 million, which was effectively settled immediately prior to the business combination. No gain or loss was recognized in the effective settlement of the deferred revenue liability. During the year ended December 31, 2022, the Company adjusted the preliminary purchase price allocation reported at December 31, 2021 to account for updates to net working capital balances. These measurement period adjustments would not have resulted in a material impact on the prior period results if the adjustments had been recognized as of the acquisition date. Furrion In September 2021, the Company acquired 100 percent of the share capital of Furrion, a leading distributor of a large range of appliances and other products to OEMs and aftermarket customers in the RV, specialty vehicle, utility trailer, horse trailer, marine, transit bus, and school bus industries. The total fair value of consideration, net of cash acquired, was approximately $146.7 million. The Company paid $50.5 million in cash consideration at closing, net of cash acquired, with fixed payments of $31.3 million due on each of the first and second anniversaries of the acquisition in September 2022 and September 2023. The Company paid the first anniversary payment in September 2022, and the remaining deferred acquisition fixed payment is recorded at its discounted present value in the Consolidated Balance Sheet in accrued expenses and other current liabilities at December 31, 2022. In 2019, the Company and Furrion agreed to terminate an exclusive distribution and supply agreement and transition all sale and distribution of Furrion products then handled by the Company to Furrion. Effective January 1, 2020, Furrion took responsibility for distributing its products directly to the customer and assumed all responsibilities previously carried out by the Company relating to Furrion products. Upon termination of the agreement, Furrion purchased from the Company all non-obsolete stock and certain obsolete and slow-moving stock of Furrion products at the cost paid by the Company. At the date of the Furrion acquisition in September 2021, the Company had a receivable balance of $35.0 million (the "Receivable from Furrion") and Furrion had a corresponding payable balance. In direct connection with the acquisition negotiations, the receivable and payable balances were effectively settled in the acquisition and the receivable balance is included within the approximate $146.7 million of consideration transferred. No gain or loss was recognized in the effective settlement of the Receivable from Furrion. The results of the acquired business have been included in the Consolidated Statements of Income since the acquisition date, in both the Company's OEM and Aftermarket Segments. As this acquisition is not considered to have a material impact on the Company's financial statements, pro forma results of operations and other disclosures are not presented.

Retirement And Other Benefit Pl

Retirement And Other Benefit Plans	12 Months Ended
	Dec. 31, 2022
Retirement Benefits [Abstract]
Retirement and Other Benefit Plans	RETIREMENT AND OTHER BENEFIT PLANS Defined Contribution Plan The Company maintains a discretionary defined contribution 401(k) profit sharing plan covering all eligible employees. The Company contributed $12.9 million, $11.6 million, and $9.0 million to this plan during the years ended December 31, 2022, 2021, and 2020, respectively. Deferred Compensation Plan The Company has an Executive Non-Qualified Deferred Compensation Plan (the "Plan"). Pursuant to the Plan, certain management employees are eligible to defer all or a portion of their regular salary and incentive compensation. Participants deferred $5.4 million, $3.1 million, and $2.9 million during the years ended December 31, 2022, 2021, and 2020, respectively. The amounts deferred under this Plan are credited with earnings or losses based upon changes in values of the notional investments elected by the Plan participants. Each Plan participant is fully vested in their deferred compensation and earnings credited to his or her account as all contributions to the Plan are made by the participant. The Company is responsible for certain costs of Plan administration, which are not significant, and will not make any contributions to the Plan. Pursuant to the Plan, payments to the Plan participants are made from the general unrestricted assets of the Company, and the Company's obligations pursuant to the Plan are unfunded and unsecured. Participants withdrew $2.4 million, $2.0 million, and $0.2 million from the Plan during the years ended December 31, 2022, 2021, and 2020, respectively. At December 31, 2022 and 2021, deferred compensation of $34.0 million and $42.6 million, respectively, was recorded in other long-term liabilities, and deferred compensation of $4.6 million and $1.1 million, respectively, was recorded in accrued expenses and other current liabilities. The Company invests approximately 100 percent of the amounts deferred by the Plan participants in life insurance contracts, matching the investments elected by the Plan participants. Deferred compensation assets and liabilities are recorded at contract value. At December 31, 2022 and 2021, life insurance contract assets of $37.6 million and $47.8 million, respectively, were recorded in other assets. Dutch Pension Plans The acquisition of Polyplastic in January 2020 included the assumption of two partially-funded defined benefit pension plans (the "Dutch pension plans") based in the Netherlands. The Dutch pension plans, which are qualified defined benefit pension plans, provided benefits based on years of service and average pay. The benefits earned by the employees were immediately vested. The Company funded the future obligations of the Dutch pension plans by purchasing non-participating annuities from a large multi-national insurance company that cover the vested pension benefit obligation of the participant, but do not cover future indexations or cost of living adjustments that were provided in plan benefits. Each year the Company made premium payments to the insurance company (1) to provide for the benefit obligation of the current year of service based on each employee's age, gender, and current salary, and (2) for indexations for both active and post-active participants. The Company determines the fair value of the plan assets with the assistance of an actuary using unobservable inputs (Level 3), which is determined as the present value of the accrued benefits guaranteed by the insurer. During 2022, there was a curtailment of the Dutch pension plans for the Company's Dutch employees whose pension benefit was based on years of service and average pay. These employees have been moved into defined contribution plans. This event resulted in curtailment gain amortization of 2.0 million for the year ended December 31, 2022. However, the unconditional indexation for all participants remains applicable and the Company remains liable for funding. No further contribution is required to fund the future accrual in the Dutch pension plans after December 31, 2022. The following table summarizes the change in the projected benefit obligation and the fair value of plan assets for the Dutch pension plans for the years ended December 31: (In thousands) 2022 2021 Projected Benefit Obligation Projected benefit obligation at beginning of period $ 85,593 $ 96,712 Interest cost 1,403 652 Net service cost 2,836 4,352 Curtailment (2,030) — Employee contributions 666 626 Benefits paid (975) (1,097) Actuarial gain, net (69,445) (8,390) Unrealized gain on foreign exchange (5,862) (7,262) Projected benefit obligation at end of period 12,186 85,593 Fair Value of Plan Assets Fair value of plan assets at beginning of period $ 52,296 $ 61,936 Increase (decrease) in plan asset value 910 (5,768) Employer contributions 1,626 1,419 Employee contributions 666 626 Benefits and administrative expenses paid (1,349) (1,377) Actuarial loss, net (43,180) — Unrealized loss on foreign exchange (3,583) (4,540) Fair value of plan assets at end of period 7,386 52,296 Underfunded status of the plans at end of the period $ 4,800 $ 33,297 Accumulated benefit obligation $ 12,186 $ 85,593 The following actuarial assumptions were used to determine the actuarial present value of the projected benefit obligation and the net periodic pension costs for the Dutch pension plans at December 31: 2022 2021 Discount rate 3.75 % 1.30 % Expected return on plan assets 3.75 % 1.30 % Wage inflation 2.00 % 2.00 % The discount rate used to determine the projected benefit obligation at December 31, 2022 was increased from 1.30 percent to 3.75 percent, consistent with a general increase in interest rates in Europe for AA-rated long-term Euro company bonds. Additionally, the Company assumed expected indexation that conforms to the industry-wide pension fund PG, as agreed upon in the Dutch pension plans, which ranged from 0.5 percent in 2022 to 2.0 percent in 2034 and thereafter for the year ended December 31, 2021, and 7.0 percent in 2023 and from 0.45 percent in 2024 to 2.0 percent in 2035 and thereafter for the year ended December 31, 2022. Amounts recognized for the Dutch pension plans in the Consolidated Balance Sheets consisted of the following at December 31: (In thousands) 2022 2021 Deferred taxes $ 1,200 $ 8,594 Other long-term liabilities 4,800 33,297 Accumulated other comprehensive income 28,125 2,107 The components of net periodic pension cost for the Dutch pension plans included the following for the years ended December 31: (In thousands) 2022 2021 2020 Net service cost $ 2,836 $ 4,352 $ 3,357 Interest cost 1,403 652 1,007 Expected return on plan assets (910) (424) (626) Amortization of actuarial gain (262) — — Amortization of curtailment (2,030) — — Administrative charges 374 280 276 Net periodic pension cost $ 1,411 $ 4,860 $ 4,014 Plan assets at December 31, 2022 consisted of insurance contracts. Under Dutch pension law, the pension insurer is legally required to pay the funded benefits to the participants. The insurer cannot unilaterally return the obligation to the employer and the employer has no risks related to the assets. As the surrender value of the contract is less than the guarantee value provided by the insurer, the guarantee value is used as the fair value of the plan assets. This value is the net present value of the accrued benefits against the same assumptions as applied in the valuation of the liability. As such, the expected return is equal to the discount rate. The Company's 2023 remaining balance sheet liability for future indexations is expected to be $0.7 million. The estimate of future annual contributions is based on current funding and the unconditional indexation requirements, and the Company believes these contributions will be sufficient to fund the Dutch pension plans. Expected benefit payments to eligible participants under the Dutch pension plans for the next ten years are as follows (in thousands): 2023 $ 63 2024 76 2025 93 2026 116 2027 153 2028 - 2032 1,148

Long-Term Indebtedness	LONG-TERM INDEBTEDNESS Long-term debt consisted of the following at December 31: (In thousands) 2022 2021 Convertible Notes $ 460,000 $ 460,000 Term Loan 375,000 395,000 Revolving Credit Loan 289,067 403,953 Shelf-Loan Facility — 50,000 Other 3,959 5,997 Unamortized deferred financing fees (9,052) (11,988) 1,118,974 1,302,962 Less current portion (23,086) (71,003) Long-term indebtedness $ 1,095,888 $ 1,231,959 Credit Agreement The Company and certain of its subsidiaries are party to a credit agreement dated December 14, 2018 with JPMorgan Chase, N.A., as a lender and administrative agent, and other bank lenders (as amended, the "Credit Agreement"). The Credit Agreement provides for a $600.0 million revolving credit facility (of which $50.0 million is available for the issuance of letters of credit (the "LC Facility") and up to $250.0 million is available in approved foreign currencies). The Credit Agreement also provided for term loans (the "Term Loan") to the Company in an aggregate original principal amount of $400.0 million. The maturity date of the Credit Agreement is December 7, 2026. The Term Loan is required to be repaid in an amount equal to 1.25 percent of the original principal amount of the Term Loan for the first eight quarterly periods commencing with the quarter ended December 31, 2021, 1.875 percent of the original principal amount of the Term Loan for the next eight quarterly periods, and then 2.50 percent of the original principal amount of the Term Loan of each additional payment until the maturity date. The Credit Agreement also permits the Company to request an increase to the revolving and/or term loan facilities by up to an additional $400.0 million in the aggregate upon the approval of the lenders providing any such increase and the satisfaction of certain other conditions. Borrowings under the Credit Agreement in U.S. dollars are designated from time to time by the Company as (i) base rate loans which bear interest at a base rate plus additional interest ranging from 0.0 percent to 0.625 percent (0.0 percent was applicable at December 31, 2022) depending on the Company’s total net leverage ratio or (ii) term benchmark loans which bear interest at LIBOR (or a relevant benchmark replacement rate) for an interest period selected by the Company plus additional interest ranging from 0.875 percent to 1.625 percent (0.875 percent was applicable at December 31, 2022) depending on the Company’s total net leverage ratio. Foreign currency borrowings other than Pounds Sterling have the same additional interest margins applicable to term benchmark loans based on the Company's total net leverage ratio. At December 31, 2022 and 2021, the Company had $4.4 million and $27.8 million, respectively, in issued, but undrawn, standby letters of credit under the LC Facility. Availability under the Company’s revolving credit facility was $306.5 million at December 31, 2022. A commitment fee ranging from 0.150 percent to 0.225 percent (0.150 percent was applicable at December 31, 2022) depending on the Company's total net leverage ratio accrues on the actual daily amount that the revolving commitment exceeds the revolving credit exposure. Shelf-Loan Facility The Company and certain of its subsidiaries had a $150.0 million shelf-loan facility (the "Shelf-Loan Facility") with PGIM, Inc. (formerly Prudential Investment Management, Inc.) and its affiliates ("Prudential"). On March 29, 2019, the Company issued $50.0 million of Series B Senior Notes (the "Series B Notes") to certain affiliates of Prudential for a term of three years, at a fixed interest rate of 3.80 percent per annum, payable quarterly in arrears. The Series B Notes were paid in full in March 2022, and the Shelf-Loan Facility expired on November 11, 2022. Convertible Notes On May 13, 2021, the Company issued $460.0 million in aggregate principal amount of 1.125 percent Convertible Notes due 2026 in a private placement to certain qualified institutional buyers, resulting in net proceeds to the Company of approximately $447.8 million after deducting the initial purchasers' discounts and offering expenses payable by the Company. The Convertible Notes bear interest at a coupon rate of 1.125 percent per annum, payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2021. The Convertible Notes will mature on May 15, 2026, unless earlier converted, redeemed, or repurchased, in accordance with their terms. As of December 31, 2022, the conversion rate of the Convertible Notes was 6.1133 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes. The conversion rate of the Convertible Notes is subject to further adjustment upon the occurrence of certain specified events. In addition, upon the occurrence of a make-whole fundamental change (as defined in the Indenture) or upon a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such make-whole fundamental change or notice of redemption, as the case may be. Prior to the close of business on the business day immediately preceding January 15, 2026, the Convertible Notes are convertible at the option of the holders only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price (as defined in the Indenture) per share of the Company's common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 percent of the conversion price for the Convertible Notes on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the "measurement period") in which the trading price (as defined in the Indenture) per $1,000 principal amount of the Convertible Notes for each trading day of the measurement period was less than 98 percent of the product of the last reported sale price of the Company's common stock and the conversion rate on each such trading day; (3) if the Company calls such Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption; or (4) upon the occurrence of certain specified corporate events described in the Indenture. On or after January 15, 2026, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion the Company will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of the Company's common stock, or a combination of cash and shares of the Company's common stock, at the Company's election, in respect of the remainder, if any, of the Company's conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. The Company may not redeem the Convertible Notes prior to May 20, 2024. On or after May 20, 2024, the Company may redeem for cash all or any portion of the Convertible Notes, at the Company's option, if the last reported sale price of the Company's common stock has been at least 130 percent of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. Upon the occurrence of a fundamental change (as defined in the Indenture), subject to certain conditions, holders of the Convertible Notes may require the Company to repurchase for cash all or any portion of their Convertible Notes in principal amounts of $1,000 or an integral multiple thereof at a repurchase price equal to 100 percent of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest on such Convertible Notes to, but not including, the fundamental change repurchase date (as defined in the Indenture). The Convertible Notes are senior unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Convertible Notes, equal in right of payment with all the Company's liabilities that are not so subordinated, effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the named trustee or the holders of at least 25 percent of the aggregate principal amount of the outstanding Convertible Notes may declare 100 percent of the principal of, and accrued and unpaid interest, if any, on all the outstanding Convertible Notes to be due and payable. The Convertible Notes are not registered securities nor listed on any securities exchange but may be actively traded by qualified institutional buyers. The fair value of the Convertible Notes of $388.7 million at December 31, 2022 was estimated using Level 1 inputs, as it is based on quoted prices for these instruments in active markets. General At December 31, 2022, the fair value of the Company's long-term debt under the Credit Agreement approximates the carrying value, as estimated using quoted market prices and discounted future cash flows based on similar borrowing arrangements. Pursuant to the Credit Agreement, the Company shall not permit its net leverage ratio to exceed certain limits, shall maintain a minimum debt service coverage ratio, and must meet certain other financial requirements. At each of December 31, 2022 and 2021, the Company was in compliance with all such requirements and expects to remain in such compliance for the next twelve months. The Credit Agreement includes a maximum net leverage ratio covenant which limits the amount of consolidated outstanding indebtedness that the Company may incur on a trailing twelve-month EBITDA. This limitation did not impact the Company's ability to incur additional indebtedness under its revolving credit facility at December 31, 2022. The Company believes the availability of $306.5 million under the revolving credit facility under the Credit Agreement, along with its cash flows from operations, are adequate to finance the Company's anticipated cash requirements for the next twelve months.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The components of earnings before income taxes consisted of the following for the years ended December 31: (In thousands) 2022 2021 2020 United States $ 550,030 $ 378,460 $ 216,234 Foreign (24,575) 3,584 (6,753) Total earnings before income taxes $ 525,455 $ 382,044 $ 209,481 The provision for income taxes in the Consolidated Statements of Income was as follows for the years ended December 31: (In thousands) 2022 2021 2020 Current: Federal $ 114,744 $ 78,604 $ 42,541 State and local 22,998 17,044 9,165 Foreign 2,016 1,936 839 Total current provision 139,758 97,584 52,545 Deferred: Federal (3,786) 2,192 2,342 State and local (285) (517) (671) Foreign (5,206) (4,954) (3,175) Total deferred provision (9,277) (3,279) (1,504) Provision for income taxes $ 130,481 $ 94,305 $ 51,041 The Company had cash and cash equivalents of approximately $47.5 million and $62.9 million at December 31, 2022 and 2021, respectively, of which approximately 49 percent and 71 percent was held by subsidiaries in foreign countries. The Company historically reinvested all unremitted earnings of its foreign subsidiaries and affiliates, and therefore had not recognized any U.S. deferred tax liability on those earnings. However, the Tax Cuts and Jobs Act change in the U.S. taxation of foreign income led the Company to reassess its position as it relates to permanent reinvestment, and it has now determined that it will only assert permanent reinvestment in its Canadian subsidiaries. The Company examined the potential liabilities related to investments in foreign subsidiaries and concluded that there is no material deferred tax liabilities that should be recorded. The provision for income taxes differs from the amount computed by applying the federal statutory rate of 21 percent for 2022, 2021, and 2020 to income before income taxes for the following reasons for the years ended December 31: (In thousands) 2022 2021 2020 Income tax at federal statutory rate $ 110,345 $ 80,229 $ 43,991 State income tax, net of federal income tax impact 17,944 13,056 6,710 Section 162(m) permanent addback 3,784 6,153 3,015 Federal tax credits (1,638) (1,230) (1,307) Share-based payment compensation excess tax benefit (509) (1,191) (190) Other 555 (2,712) (1,178) Provision for income taxes $ 130,481 $ 94,305 $ 51,041 At December 31, 2022, the Company had domestic federal income taxes receivable of $16.6 million, domestic state income taxes receivable of $5.4 million, and foreign taxes receivable of $1.2 million recorded. At December 31, 2021, the Company had domestic federal income taxes payable of $8.5 million, domestic state income taxes payable of $1.6 million, and foreign taxes receivable of $1.6 million recorded. Deferred Income Tax Assets and Liabilities and Valuation Allowances The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows at December 31: (In thousands) 2022 2021 Deferred tax assets: Stock-based compensation $ 2,268 $ 2,632 Pension 1,271 8,594 Deferred compensation 15,091 15,923 Warranty 11,517 10,790 Convertible debt bond hedge 17,237 21,699 Inventory 20,758 16,502 Research and experimental costs 4,986 — Other 6,630 5,792 Lease obligation asset 63,146 41,066 Net operating loss, interest, and tax credit carryforwards 12,924 10,132 Total deferred tax assets before valuation allowance 155,828 133,130 Less valuation allowance (8,750) (1,054) Total deferred tax assets net of valuation allowance 147,078 132,076 Deferred tax liabilities: Lease obligation liability (60,487) (38,770) Fixed assets (45,634) (45,562) Intangible assets (67,640) (87,035) Total deferred tax liabilities (173,761) (171,367) Net deferred tax liabilities $ (26,683) $ (39,291) At December 31, 2022 and 2021, the Company had net foreign deferred tax liabilities of $19.2 million and $26.2 million, respectively, primarily related to intangible assets, foreign pension obligations, and net operating loss carryforwards net of any related valuation allowances included in other long-term liabilities on the Consolidated Balance Sheets. As of December 31, 2022, the Company had deferred tax assets recorded related to foreign net operating losses and tax credit carryforwards of $12.7 million, net. This includes $1.9 million related to U.K. entities, $3.1 million related to Italian entities, and $7.7 million related to Furrion Ltd. The net operating losses and tax credit carryforwards have indefinite lives. The foreign valuation allowance for U.K. deferred tax assets as of each of December 31, 2022 and 2021 was $0.9 million. These valuation allowances were related to net operating losses and tax credit carryforwards related to the U.K. entities. During 2022, the Company finalized purchase accounting for its Hong Kong-based entity that it acquired in the Furrion acquisition in 2021. As a result of this purchase accounting, the Company placed a full valuation allowance on the $7.7 million of deferred tax assets in Hong Kong. Based upon historical results and estimated future results, it is the judgment of management that these tax carryforward attributes related to the U.K. and Hong Kong entities are not likely to be realized. The Company has concluded it is more likely than not that it will realize the benefit of all other existing deferred tax assets, net of the valuation allowances mentioned above. Unrecognized Tax Benefits The following table reconciles the total amounts of unrecognized tax benefits, at December 31: (In thousands) 2022 2021 2020 Balance at beginning of period $ 20,462 $ 8,921 $ 8,214 Changes in tax positions of prior years — (69) — Additions based on tax positions related to the current year 5,758 12,826 1,720 Decreases due to settlements of liabilities (904) — — Closure of tax years (1,940) (1,216) (1,013) Balance at end of period $ 23,376 $ 20,462 $ 8,921 In addition, the total amount of accrued interest and penalties related to taxes, recognized as a liability, was $5.1 million, $0.8 million, and $0.7 million at December 31, 2022, 2021, and 2020, respectively. The increase in 2022 compared to the prior year is a result of additional interest and penalties that were recorded as part of purchase accounting. The total amount of unrecognized tax benefits, net of federal income tax benefits, of $27.5 million, $20.5 million, and $8.8 million at December 31, 2022, 2021, and 2020, respectively, would, if recognized, increase the Company’s earnings, and lower the Company's annual effective tax rate in the year of recognition. The year over year increase in 2022 in the total amount of unrecognized tax benefits was to reflect a reserve recorded as part of a prior year acquisition which was still within the one-year purchase accounting window. The Company is subject to taxation in the United States and various states and foreign jurisdictions. In the normal course of business, the Company is subject to examinations by taxing authorities in these jurisdictions. For U.S. state income tax purposes, tax years 2021, 2020, and 2019 remain subject to examination. During 2022, the Company settled an examination with the U.S. Internal Revenue Service for the tax years 2020, 2019, and 2018. The Company has assessed its risks associated with all tax return positions and believes its tax reserve estimates reflect its best estimate of the deductions and positions it will be able to sustain, or it may be willing to concede as part of a settlement. At this time, the Company does not anticipate any material change in its tax reserves in the next twelve months. The Company will continue to monitor the progress and conclusion of all audits and will adjust its estimated liability as necessary.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Holdback Payments and Contingent Consideration From time to time, the Company finances a portion of its business combinations with deferred acquisition payments ("holdback payments") and/or contingent earnout provisions. Holdback payments are accrued at their discounted present value. As required, the liability for contingent consideration is measured at fair value quarterly, considering actual sales of the acquired products, updated sales projections, and the updated market participant weighted average cost of capital. Depending upon the weighted average costs of capital and future sales of the products which are subject to contingent consideration, the Company could record adjustments in future periods. See Note 4 - Acquisitions, Goodwill and Other Intangible Assets for details of holdback payments. Contingent consideration balances were not material at December 31, 2022 and 2021. Product Recalls From time to time, the Company cooperates with and assists its customers on their product recalls and inquiries, and occasionally receives inquiries directly from the National Highway Traffic Safety Administration regarding reported incidents involving the Company's products. As a result, the Company has incurred expenses associated with product recalls from time to time and may incur expenditures for future investigations or product recalls. Environmental The Company's operations are subject to certain Federal, state and local regulatory requirements relating to the use, storage, discharge, and disposal of hazardous materials used during the manufacturing processes. Although the Company believes its operations have been consistent with prevailing industry standards and are in substantial compliance with applicable environmental laws and regulations, one or more of the Company's current or former operating sites, or adjacent sites owned by third-parties, have been affected, and may in the future be affected, by releases of hazardous materials. As a result, the Company may incur expenditures for future investigation and remediation of these sites, including in conjunction with voluntary remediation programs or third-party claims. Litigation In the normal course of business, the Company is subject to proceedings, lawsuits, regulatory agency inquiries, and other claims. All such matters are subject to uncertainties and outcomes that are not predictable with assurance. While these matters could materially affect operating results when resolved in future periods, management believes that, after final disposition, including anticipated insurance recoveries in certain cases, any monetary liability or financial impact to the Company beyond that provided in the Consolidated Balance Sheet as of December 31, 2022, would not be material to the Company's financial position or annual results of operations.

Executive officers and other employees of the Company and its subsidiaries and affiliates, and independent directors, consultants, and others who provide substantial services to the Company and its subsidiaries and affiliates, are eligible to be granted awards under the 2018 Plan. Under the 2018 Plan, the Compensation Committee of LCII's Board of Directors is authorized to grant stock options, stock appreciation rights, restricted stock awards, stock unit awards, other stock-based awards, and cash incentive awards. The number of shares available for future awards under the 2018 Plan was 1,032,403, 1,195,993, and 1,300,115 at December 31, 2022, 2021, and 2020, respectively. Stock-based compensation resulted in charges to operations as follows for the years ended December 31: (In thousands) 2022 2021 2020 Deferred and restricted stock units $ 15,594 $ 16,487 $ 14,329 Stock awards 8,101 10,674 4,173 Stock-based compensation expense $ 23,695 $ 27,161 $ 18,502 Stock-based compensation expense is recorded in the Consolidated Statements of Income in the same line as cash compensation to those employees is recorded, primarily in selling, general and administrative expenses. Deferred and Restricted Stock Units The 2018 Plan provides for the grant or issuance of stock units, including those that have deferral periods, such as deferred stock units ("DSUs"), and those with time-based vesting provisions, such as restricted stock units ("RSUs"), to directors, employees and other eligible persons. Recipients of DSUs and RSUs are entitled to receive shares at the end of a specified vesting or deferral period. Holders of DSUs and RSUs receive dividend equivalents based on dividends granted to holders of the common stock, which dividend equivalents are payable in additional DSUs and RSUs, and are subject to the same vesting criteria as the original grant. DSUs vest (i) ratably over the service period, (ii) at a specified future date, or (iii) for certain officers, based on achievement of specified performance conditions. RSUs vest (i) ratably over the service period or (ii) at a specified future date. As a result of the Company's executive succession, the vesting of certain RSUs was accelerated pursuant to contractual obligations with certain employees whose employment terminated. In addition, DSUs are issued in lieu of certain cash compensation. Transactions in DSUs and RSUs under the 2018 Plan are summarized as follows: Number of Shares Weighted Average Price Outstanding at December 31, 2019 346,148 $ 87.54 Issued 5,703 97.42 Granted 150,319 97.70 Dividend equivalents 10,042 95.08 Forfeited (21,856) 91.79 Vested (155,269) 87.69 Outstanding at December 31, 2020 335,087 $ 90.04 Issued 4,653 137.62 Granted 109,767 142.37 Dividend equivalents 7,233 134.78 Forfeited (6,696) 114.66 Vested (164,333) 87.64 Outstanding at December 31, 2021 285,711 $ 110.41 Issued 5,427 101.87 Granted 162,719 119.84 Dividend equivalents 10,871 103.27 Forfeited (15,012) 121.99 Vested (171,942) 96.21 Outstanding at December 31, 2022 277,774 $ 120.92 As of December 31, 2022, there was $18.4 million of total unrecognized compensation cost related to DSUs and RSUs, which is expected to be recognized over a weighted average remaining period of 1.3 years. Performance Stock Units The 2018 Plan provides for performance stock units ("PSUs") that vest at a specific future date based on achievement of specified performance conditions. Transactions in PSUs under the 2018 Plan are summarized as follows: Number of Shares Stock Price Outstanding at December 31, 2019 129,128 $ 96.21 Granted 66,029 98.98 Dividend equivalents 3,303 96.54 Forfeited (73,581) 107.91 Vested (5,152) 100.46 Outstanding at December 31, 2020 119,727 $ 89.92 Granted 40,102 143.54 Dividend equivalents 3,778 134.82 Forfeited (1,053) 96.55 Vested (12,593) 95.03 Outstanding at December 31, 2021 149,961 $ 104.01 Granted 91,988 110.83 Dividend equivalents 6,210 103.29 Forfeited (4,840) 78.11 Vested (80,938) 82.40 Outstanding at December 31, 2022 162,381 $ 120.12 As of December 31, 2022, there was $7.7 million of total unrecognized compensation cost related to PSUs, which is expected to be recognized over a weighted average remaining period of 0.9 years.

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING The Company has two reportable segments, the OEM Segment and the Aftermarket Segment. Intersegment sales are insignificant. The OEM Segment, which accounted for 83 percent, 81 percent, and 78 percent of consolidated net sales for each of the years ended December 31, 2022, 2021, and 2020, respectively, manufactures and distributes a broad array of engineered components for the leading OEMs in the recreation and industrial product markets, consisting of RVs and adjacent industries, including boats; buses; trailers used to haul boats, livestock, equipment, and other cargo; trucks; trains; manufactured homes; and modular housing. Approximately 61 percent, 63 percent, and 61 percent of the Company's OEM Segment net sales in 2022, 2021, and 2020, respectively, were of components for travel trailer and fifth-wheel RVs. The Aftermarket Segment, which accounted for 17 percent, 19 percent, and 22 percent of consolidated net sales for each of the years ended December 31, 2022, 2021, and 2020, respectively, supplies engineered components to the related aftermarket channels of the recreation and transportation product markets, primarily to retail dealers, wholesale distributors, and service centers, as well as direct to retail customers via the Internet. The Aftermarket Segment also includes biminis, covers, buoys, fenders to the marine industry, towing products, truck accessories, appliances, air conditioners, televisions, sound systems, tankless water heaters, and the sale of replacement glass and awnings to fulfill insurance claims. Decisions concerning the allocation of the Company's resources are made by the Company's Chief Operating Decision Maker ("CODM"), with oversight by the Board of Directors. The CODM evaluates the performance of each segment based upon segment operating profit or loss, generally defined as income or loss before interest and income taxes. Decisions concerning the allocation of resources are also based on each segment's utilization of assets. Management of debt is a corporate function. The accounting policies of the OEM and Aftermarket Segments are the same as those described in Note 2 of the Notes to Consolidated Financial Statements.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	The Consolidated Financial Statements include the accounts of LCI Industries and its wholly-owned subsidiaries ("LCII" and collectively with its subsidiaries, the "Company," "we," "us," or "our"). LCII has no unconsolidated subsidiaries. LCII, through its wholly-owned subsidiary, Lippert Components, Inc. and its subsidiaries (collectively, "Lippert Components," "LCI," or "Lippert"), supplies, domestically and internationally, a broad array of engineered components for the leading original equipment manufacturers ("OEMs") in the recreation and transportation product markets, consisting primarily of recreational vehicles ("RVs") and adjacent industries including boats; buses; trailers used to haul boats, livestock, equipment, and other cargo; trucks; trains; manufactured homes; and modular housing. The Company also supplies engineered components to the related aftermarkets of these industries, primarily by selling to retail dealers, wholesale distributors, and service centers, as well as direct to retail customers via the Internet. At December 31, 2022, the Company operated over 130 manufacturing and distribution facilities located throughout North America and Europe. Most industries where the Company sells products or where its products are used historically have been seasonal and are generally at the highest levels when the weather is moderate. Accordingly, the Company's sales and profits have generally been the highest in the second quarter and lowest in the fourth quarter. However, current and future seasonal industry trends have been, and may in the future be, different than in prior years due to various factors, including fluctuations in dealer inventories and the timing of dealer orders, the impact of international, national, and regional economic conditions and consumer confidence on retail sales of RVs and other products for which the Company sells its components, the impact of severe weather conditions on the timing of industry-wide shipments from time to time, as well as the coronavirus ("COVID-19") pandemic and related impacts. Additionally, many of the optional upgrades and non-critical replacements for RVs are purchased outside the normal product selling season, thereby causing certain Aftermarket Segment sales to be counter-seasonal, but this has been, and may in the future be, different as a result of the COVID-19 pandemic and the continuing impact of market and supply chain disruptions. The Company is not aware of any significant events which occurred subsequent to the balance sheet date but prior to the filing of this report that would have a material impact on the Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated. Certain prior year balances have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to product returns, sales and purchase rebates, accounts receivable, inventories, goodwill and other intangible assets, net assets of acquired businesses, income taxes, warranty and product recall obligations, self-insurance obligations, operating lease right-of-use assets and obligations, asset retirement obligations, long-lived assets, pension and post-retirement benefits, stock-based compensation, segment allocations, contingent consideration, environmental liabilities, contingencies, and litigation. The Company bases its estimates on historical experience, other available information, and various other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other resources. Actual results and events could differ significantly from management estimates. Risks and Uncertainties The COVID-19 pandemic and the conflict between Russia and Ukraine (the "Russia-Ukraine War") have caused significant uncertainty and disruption in the global economy and financial markets. Management continues to closely monitor the impact of COVID-19 and the Russia-Ukraine War, as well as heightened tensions between China and Taiwan, on all aspects of the business. The extent to which COVID-19, the Russia-Ukraine War, and/or relations between China and Taiwan may impact the Company's liquidity, financial condition, and results of operations in the future remains uncertain.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents.
Accounts Receivable	Accounts Receivable Accounts receivable are stated at historical carrying value, net of write-offs and allowances. The Company establishes allowances based upon historical experience, current conditions, and reasonable forecasts. Uncollectible accounts receivable are written off when a settlement is reached or when the Company has determined the balance will not be collected.
Inventories	Inventories Inventories are stated at the lower of cost (using the first-in, first-out (FIFO) method) or net realizable value. Cost includes material, labor, and overhead.
Fixed Assets	Fixed Assets Fixed assets which are owned are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over the estimated useful lives of the properties and equipment. Leasehold improvements and leased equipment are amortized over the shorter of the lives of the leases or the underlying assets. Maintenance and repair costs that do not improve service potential or extend economic life are expensed as incurred.
Leases	Leases The Company leases certain manufacturing and distribution facilities, administrative office space, semi-tractors, trailers, forklifts, and other equipment through operating leases with unrelated third parties. At contract inception, the Company determines whether a contract is or contains a lease and whether the lease should be classified as an operating or finance lease. The Company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments over the lease term at the commencement date. The Company uses its incremental borrowing rate based on information available at lease inception in determining the present value of the lease payments. The Company applies a portfolio approach for determining the incremental borrowing rate based on applicable lease terms and the current economic environment. Many of the Company's leases include renewal options, which are included in the lease term when it is reasonably certain the option will be exercised. Leases with an initial term of 12 months or less are recognized in lease expense on a straight-line basis over the lease term and not recorded on the Consolidated Balance Sheets. Certain of the Company's lease arrangements contain lease components (such as minimum rent payments) and non-lease components (such as common-area or other maintenance costs and taxes). The Company generally accounts for each component separately based on the estimated standalone price of each component. Some of the Company's lease arrangements include rental payments that are adjusted periodically for an index rate. These leases are initially measured using the projected payments in effect at the inception of the lease. Certain of the Company's leased semi-tractors, trailers, and forklifts include variable costs for usage or mileage. Such variable costs are expensed as incurred and included in variable lease costs. Finance leases and lease arrangements under which the Company is the lessor are not material to the Company's consolidated financial statements. The Company's lease agreements typically do not contain any significant residual value guarantees or restrictive covenants.
Warranty	Warranty The Company provides warranty terms based upon the type of product sold. The Company estimates the warranty accrual based upon various factors, including historical warranty costs, warranty claim lag, and sales. The accounting for warranty accruals requires the Company to make assumptions and judgments, and to the extent actual results differ from original estimates, adjustments to recorded accruals may be required. See Note 7 - Accrued Expenses and Other Current Liabilities for further detail.
Income Taxes	Income Taxes Deferred tax assets and liabilities are determined based on the temporary differences between the financial reporting and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all the deferred tax assets will not be realized. The Company accounts for uncertainty in tax positions by recognizing in its financial statements the impact of a tax position only if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Further, the Company assesses the tax benefits of the tax positions in its financial statements based on experience with similar tax positions, information obtained during the examination process and the advice of experts. The Company recognizes previously unrecognized tax benefits upon the earlier of the expiration of the period to assess tax in the applicable taxing jurisdiction or when the matter is constructively settled and upon changes in statutes or regulations and new case law or rulings. The Company classifies interest and penalties related to income taxes as a component of income tax expense in its Consolidated Statements of Income.
Goodwill	Goodwill Goodwill represents the excess of the total consideration given in an acquisition of a business over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested at the reporting unit level for impairment annually in November, or more frequently if certain circumstances indicate a possible impairment may exist. In 2022 and 2021, the Company assessed qualitative factors of its reporting units to determine whether it was more likely than not the fair value of the reporting unit was less than its carrying amount, including goodwill. The qualitative impairment test consists of an assessment of qualitative factors, including general economic and industry conditions, market share, and input costs.
Other Intangible Assets	Other Intangible Assets Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment. Intangible assets are amortized using either an accelerated or straight-line method, whichever best reflects the pattern in which the estimated future economic benefits of the asset will be consumed. The useful lives of intangible assets are determined after considering the expected cash flows and other specific facts and circumstances related to each intangible asset. Intangible assets with indefinite lives are not amortized, but instead are tested for impairment annually in November, or more frequently if certain circumstances indicate a possible impairment may exist.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets, other than goodwill, are tested for impairment when changes in circumstances indicate their carrying value may not be recoverable. A determination of impairment, if any, is made based on the undiscounted value of estimated future cash flows, salvage value or expected net sales proceeds, depending on the circumstances. Impairment is measured as the excess of the carrying value over the estimated fair value of such assets.
Foreign Currency Translation	Foreign Currency Translation The financial statements of the Company's international subsidiaries generally are measured using the local currency as the functional currency. The translation from the applicable foreign currency to U.S. Dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using the weighted average exchange rate for the period. The resulting translation adjustments are recorded in accumulated other comprehensive income as a component of stockholders' equity. The Company reflects net foreign exchange transaction gains and losses resulting from the conversion of the transaction currency to functional currency as a component of foreign currency exchange gains or losses in selling, general and administrative expenses in the Consolidated Statements of Income.
Stock-Based Compensation	Stock-Based Compensation All stock-based compensation awards are expensed over their vesting period, based on fair value. For awards having a service-only vesting condition, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service periods. For awards with a performance vesting condition, which are subject to certain pre-established
Revenue recognition	Revenue Recognition The Company recognizes revenue when performance obligations under the terms of contracts with customers are satisfied, which occurs with the transfer of control of the Company’s products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring its products to its customers. Sales, value added, and other taxes collected concurrent with revenue-producing activities are excluded from revenue. For the vast majority of product sales, the Company transfers control and recognizes revenue when it ships the product from its facility to its customer. The amount of consideration the Company receives, and the revenue recognized varies with sales discounts, volume rebate programs, and indexed material pricing. When the Company offers customers retrospective volume rebates, it estimates the expected rebates based on an analysis of historical experience. The Company adjusts its estimate of revenue related to volume rebates at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. Volume rebates are generally settled on a quarterly basis. When the Company offers customers prompt pay sales discounts or agrees to variable pricing based on material indices, it estimates the expected discounts or pricing adjustments based on an analysis of historical experience. The Company adjusts its estimate of revenue related to sales discounts and indexed material pricing to the expected value of the consideration to which the Company will be entitled. The Company includes the variable consideration in the transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur when the volume, discount or indexed material price uncertainties are resolved. See Note 15 - Segment Reporting for the Company's disclosures of disaggregated revenue. Shipping and Handling Costs
