As an owner of a "vintage" camper, would just give you a heads up. Refrigerators and stoves go out but can be replaced. How are the curtains? They are usually custom made to replace. How is the mattress, the flooring? Cabinet hardware is hard to find.
I haven’t looked inside. One thing I did notice from the outside is the aluminum siding is very slightly bubbled out right above and behind the cab. I’m wondering if that means the inner structure is crushed or something like that.
