Sarah, buying the Owner's Manual will be a great investment. You can get reproductions from Helen Davis at Secretarial Services, PO Box 484, Sidney, OH 45365 (937) 492-8885. I don't have the same model trailer as you, so can't answer the questions. Buying the manual, and reading it carefully, cover-to-cover, will be time well spent.
