Hard to say without looking, but I think you may be able to find another or get this for less. My Argosy I traded a boat for that was worth a few thousand. The trailer didn't have any real structural issues, just lots of renovation/painting etc. Its been a lot of opportunities for me to personalize it and update things, and I have enjoyed (most of the time) working on it.
I have seen a lot of Excella 31s for sale, they seemed to make a bunch of them and they always seem to be some of the lower priced ones on the market.
I have replaced a water heater, A/C, counter-tops, flooring and lots of other little things. Have probably spent $3000 on it since I received it six months ago.
Only wood in my argosy is thin plywood veneer used for bulkhead walls and the floor is plywood.
