Two years ago I was at the point you are. I had a nice 1ton truck that was paid for and a nice 35' 5th wheel that was not paid for. I went about it this way. Went to dealers and looked around without saying much about tradeins or fianicing. Once I made my decission on the new class A I told the dealer I wanted to trade my 5th wheel and tow truck in. Lets face it the dealer is not going to loose money, but for me it was easier than trying to sell the old myself. After some good old give and take I was happy with the finial result.
