We are familiar with the proceedings to date in connection with the proposed issuance and sale of Asset Backed Notes (the "1999-3 Notes") by Distribution Financial Services RV Trust 1999-3 (the "Trust"), and in order to express our opinion hereinafter stated we have examined and relied upon the following items relating to the 1999-3 Notes and the Trust: the Trust Agreement, the Amended and Restated Trust Agreement, the Transfer and Servicing Agreement, the Indenture, the DFS/Ganis Transfer Agreement, the Ganis/Depositor Transfer Agreement, and the 1999-3 Notes (such Trust Agreement, Amended and Restated Trust Agreement, Transfer and Servicing Agreement, Indenture, DFS/Ganis Transfer Agreement, Ganis/Depositor Transfer Agreement and 1999-3 Notes being referred to collectively as the "1999-3 Documents"). We have also examined such statutes, corporate records and other instruments as we have deemed necessary for the purposes of this opinion. Based on and subject to the foregoing, we are of the opinion that, with respect to the 1999-3 Notes, when: (a) the 1999-3 Documents have each been duly (i) authorized by the parties thereto (other than by the Depositor) and (ii) completed, executed and delivered by all of the parties thereto, (b) the related Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, (c) the 1999-3 Notes have been duly executed and issued by the Trust and authenticated by the Indenture Trustee named therein, and sold by the Company or by the Trust, at the direction of the Company or the Trust, as applicable, and (d) payment of the agreed consideration for the 1999-3 Notes shall have been received by the Company or the Trust, all in accordance with the terms and conditions of the 1999-3 Documents and a definitive purchase, underwriting or similar agreement with respect to the 1999-3 Notes: the 1999-3 Notes will have been duly authorized by all necessary action of the Trust and will be legally issued and binding obligations of the Trust and entitled to the benefits afforded by the related Indenture, except as may be limited by bankruptcy, insolvency, reorganization, arrangement, moratorium or other laws relating to or affecting creditors' rights generally (including, without limitation, fraudulent conveyance laws), and by general principles of equity, regardless of whether such matters are considered in a proceeding in equity or at law. Our opinions expressed herein are limited to the federal laws of the United States and the laws of the State of New York. We hereby consent to the filing of this opinion with the Securities and Exchange Commission. Very truly yours, /s/ Mayer, Brown & Platt MAYER, BROWN & PLATT 2
