Thanks for the input. As for the hydraulic lifting system, I would think all hoses should be replaced on a 20 year old system. The owner already had to replace a hose on the pump that ruptured as they were preparing to take the camper out for the first time this year.
It's a pretty nice unit, and would work for us, especially if I replaced one or both pull out beds with folding walls. But, I can't see paying anywhere near $3900 for it. A quick NADA check for it came up with about $1800 east of the Mississippi; also stated higher west of Mississippi. But, I doubt it would be double.
By the way, did you use plywood for the new walls and piano hinges? My thought was to use 1" Styrofoam with maybe a 1"x2" frame, and piano hinges. That would give me some insulation. I would also install a window from one of the RV salvagers in the area.
Post more pictures when you can.
