STOCK PURCHASE AGREEMENT

                                 I.  The Parties

   The Parties to this Agreement are:

   1.01      Oshkosh Truck Corporation, a Wisconsin corporation, located
             at 2307 Oregon Street, Oshkosh, Wisconsin ("Oshkosh").

   1.02      J. Peter Mosling, Jr., an adult resident of Pickett, Wisconsin
             ("Peter").

   1.03      Stephen P. Mosling, an adult resident of Oshkosh, Wisconsin
             ("Stephen").

                                II.  The Recitals

   2.01      The Date of this Agreement is the 26th day of April, 1996.

   2.02      Peter and Stephen, together, are the individual owners of a
             substantial majority of the issued and outstanding shares of
             Class A Common Stock of Oshkosh (such shares that Peter and
             Stephen own individually are collectively referred to as
             "Shares").

   2.03      The Parties desire to establish the circumstances, terms and
             conditions under which Oshkosh will acquire the Shares, to
             impose certain limitations upon the transferability of Shares by
             Peter and Stephen in the interim, and to provide ultimately for
             conversion of all issued and outstanding shares of Class A
             Common Stock of Oshkosh into shares of its Class B Common Stock.

   2.04      The number of issued and outstanding shares of Class A Common
             Stock on the Date of this Agreement are 409,503.  Of these,
             Peter owns individually 119,813 shares, and Stephen owns
             individually 120,892 shares.  Class A shares owned indirectly or
             beneficially by either of them through Cadence Company, a
             Wisconsin general partnership, are not intended to be subject to
             this Agreement.  Class A shares owned by Stephen as Trustee for
             Melissa K. Mosling also are not intended to be subject to this
             Agreement.

   2.05      Previously, in connection with execution by Oshkosh of a
             Strategic Alliance Agreement with Freightliner Corporation on
             June 2, 1995, Peter and Stephen agreed to certain limitations
             upon the transferability of their Shares, and it is the
             intention of the Parties that this Agreement be effective
             independent from the effect of that agreement.

   2.06      The Class B Common Stock of Oshkosh is publicly traded on NASDAQ
             and registered with the Securities and Exchange Commission.  The
             Class A Common Stock is not registered with the Securities and
             Exchange Commission and is publicly traded only on occasion.

                               III.  The Agreement

   3.01      The Recitals.  The Recitals are a part of this Agreement.

   3.02      Restrictions on Sale or Transfer by Peter and Stephen.  Except
             as provided by this Agreement, and as limited by the agreement
             dated June 2, 1995, Peter and Stephen agree that they will not
             transfer, sell or otherwise dispose of any shares which either
             of them now or in the future may own directly in their own
             names.

             3.021     A pledge of Shares shall not be considered a transfer,
                       sale or other disposition, but a levy upon or
                       foreclosure of a pledge shall be deemed to be a sale
                       or other disposition.

             3.022     Peter and Stephen each may transfer Shares to the
                       other, or to trusts for the respective benefit of each
                       or the other, including voting trusts in which at
                       least one of them serves as trustee and, as such, or
                       as otherwise provided by the trust, shall have the
                       full and unrestricted authority, power and discretion
                       to vote such Shares on all matters as to which the
                       Shares may be voted.

             3.023     Peter and Stephen each may transfer Shares to trusts
                       which are effective upon the death of the transferor,
                       whether testamentary or otherwise, in which at least
                       one of them serves as a trustee and, as such, or as
                       otherwise provided by the trust, shall have the full
                       and unrestricted authority, power and discretion to
                       vote such Shares on all matters as to which the Shares
                       may be voted.

             3.024     Peter and/or Stephen each may transfer Shares to R.
                       Eugene Goodson pursuant to a certain letter agreement
                       dated June 25, 1990.

             3.025     Transfers to a pledgee or Trustee, under this Section
                       3.02, or to Mr. Goodson shall be subject to all of the
                       terms and conditions of this Agreement, and any
                       further transfer of Shares by any such pledgee or
                       Trustee or by Mr. Goodson, except to a permitted
                       transferee under this Section shall be deemed a
                       prohibited transfer, sale or other disposition of the
                       Shares.

             3.026     Peter and Stephen each may exchange Shares for shares
                       of Class B Common Stock of Oshkosh at any time(s) and
                       in any amount.  To the extent that they transfer
                       Shares as permitted by this Section 3.02, their
                       transferees also may exchange Shares for shares of
                       Class B Common Stock.  When exchanged, such shares of
                       Class B Common Stock shall be free from the terms and
                       conditions of this Agreement.  Notwithstanding the
                       foregoing, Peter and/or Stephen and/or any such
                       transferee, will not exchange Shares if, following
                       such exchange, the remaining Shares would not
                       constitute a majority of the outstanding Class A
                       Common Stock on a fully diluted basis unless the
                       amendment contemplated by Section 3.03 has been
                       effected.

   3.03      Covenant to Act to Amend the Articles of Incorporation of
             Oshkosh.  Peter and Stephen each agree that in the event the
             Board of Directors of Oshkosh at any time proposes to its
             Shareholders that the Articles of Incorporation of Oshkosh be
             amended to provide a mechanism for mandatory conversion of
             issued and outstanding shares of Class A Common Stock so that
             Oshkosh will have only one issued and outstanding class of
             common stock, with such conversion to occur upon the earliest to
             occur of:

             3.031     The death of the survivor of Peter and Stephen;

             3.032     The legal incapacity of Peter and/or Stephen under
                       circumstances in which neither of them has the legal
                       capacity and capability to vote a majority of the
                       issued and outstanding shares of Class A Common Stock
                       of Oshkosh at that time, which incapacity thereafter
                       continues for a period of time which includes the date
                       of regularly-scheduled annual meeting of the
                       shareholders of Oshkosh and two hundred seventy (270)
                       days following such date; or

             3.033     The number of issued and outstanding shares of Class A
                       Common Stock of Oshkosh beneficially owned by Peter
                       and/or Stephen falls for any reason below 150,000
                       shares, or such higher number as may be agreed upon by
                       the Parties;

             they will vote their Class A Common Stock shares in favor of
             such an amendment, and will cause any trustee or pledgee of
             Shares to vote in favor of such an amendment.

   3.04      Covenant to Act to Eliminate Class A Stock.  Peter and Stephen
             each agree that in the event of the death of the survivor of
             them, or in the event that at an earlier time neither of them
             has the legal capacity and capability to vote a majority of the
             issued and outstanding shares of Class A Common Stock of
             Oshkosh, then they or their legal representatives and trustees,
             if any, promptly shall exert their best efforts to cause Oshkosh
             to do all things necessary to effect a prompt and orderly
             elimination, whether by conversion into shares of Class B Common
             Stock of Oshkosh or otherwise, of all issued and outstanding
             shares of Class A Common Stock of Oshkosh.  They also agree that
             they and their legal representatives and trustees, if any,
             promptly shall take such actions, including the tender of Shares
             for shares of Class B Common Stock, as may be necessary to
             require the conversion of all issued and outstanding shares of
             Class A Common Stock of Oshkosh so that Oshkosh will have only
             one class of issued and outstanding common stock.

             3.041     Notwithstanding anything to the contrary provided by
                       this Section or elsewhere by this Agreement, no action
                       shall be required of Peter, Stephen or their legal
                       representatives or trustees which would have the
                       effect of eliminating Shares other than in the context
                       of a simultaneous conversion of all other issued and
                       outstanding shares of Class A Common Stock of Oshkosh.

             3.042     In the event of action by Oshkosh to amend its
                       Articles of Incorporation as set forth in Section
                       3.03, Peter and Stephen each shall give Oshkosh an
                       irrevocable notice of conversion of their Shares in a
                       form sufficient to give effect to their covenants in
                       this Section 3.04.

   3.05      Action by Oshkosh.  In the absence of prior action by Oshkosh
             under Section 3.03, above, Oshkosh agrees that upon receipt of a
             request by Peter and Stephen, or their legal representatives or
             trustees, or in the event of the death of either of them by the
             survivor of them, or his legal representatives, to undertake the
             cancellation and elimination of the authorization of its shares
             of Class A Common Stock, it will act promptly to call a meeting
             of the necessary shareholders of Oshkosh at an appropriate time
             and place for the purposes of amending the Articles of
             Incorporation of Oshkosh in order to eliminate from the capital
             structure of Oshkosh the authorization of Class A Common Stock,
             and for such other actions as Oshkosh shall deem necessary or
             appropriate in order to redeem or otherwise cancel all then
             issued and outstanding shares of Class A Common Stock.

   3.06      Consideration.  Oshkosh has determined that if Peter and Stephen
             were to cease to be owners of their Shares, and others were to
             become owners of a majority of the shares of Class A Common
             Stock, it would not be in the interests of the other
             shareholders of Oshkosh.  In consideration of the agreements of
             Peter and Stephen set forth above, Oshkosh shall pay to each of
             them the sum of FIFTY THOUSAND DOLLARS ($50,000.00) upon
             execution of this Agreement.

   3.07      Stock Certificate Legend.  Upon execution of this Agreement the
             certificates representing the Shares shall be surrendered to
             Oshkosh by Peter and Stephen for the purpose of placing on each
             such certificate a printed legend which is appropriate to
             disclose the substance of the restrictions on transferability
             and other covenants imposed by this Agreement on the Shares,
             after which the certificates promptly shall be returned to Peter
             and Stephen.

   3.08      Covenant Against Transfer.  While this Agreement is in force and
             effect, Oshkosh shall not transfer Shares except in compliance
             with the provisions of this Agreement.

   3.09      Specific Enforcement.  Upon the death of the survivor of Peter
             and Stephen or the earlier legal incapacity of Peter and/or
             Stephen under circumstances in which neither of them has the
             legal capacity and capability to vote a majority of the issued
             and outstanding shares of Class A Common Stock of Oshkosh, if
             his legal representative, including any trustee, guardian,
             conservator or holder of an appropriate durable power, shall
             fail for any reason within thirty (30) days of such event to
             request Oshkosh to take actions contemplated under Sections 3.03
             and 3.04 of this Agreement, Oshkosh may specifically enforce
             this Agreement, including the court appointment of such a legal
             representative if there be none.

   3.10      Schedule 13D Filing.  Peter and Stephen each shall file a
             Securities and Exchange Commission Schedule 13D within ten (10)
             days after execution of this Agreement.

   3.11      Binding Agreement.  This Agreement shall bind the Parties, their
             legal representatives, heirs, successors and assigns.

        Executed by the Parties on the Date of this Agreement.

                                 OSHKOSH TRUCK CORPORATION:

        R. Eugene Goodson hereby consents, to the extent necessary in
