I want to rehabilitate my old Dodge Class C

As a young family with a small budget, and not having much mechanical and RV repair know-how, we bought an old leaky, smelly 1979 "orphan" rig for $13K that looked nice externally but had been a rental before the previous owners bought it. Turned out that it needed serious engine and cooling system overhaul, roof and dash air conditioner repair, RV generator overhaul, tires, etc, etc. We spent another $8K on it the first year and got it "running good enough" to even do some serious touring and camping even though the rig was still old, had leaks and mold smell, as well as a very poor floor plan for our needs.If we knew what we were doing, we would have saved our money and bought a much newer and better conditioned rig that suited our needs much better for $21K. If you can actually do most of the overhaul, repair and replacement work yourself, in a reasonable period of time, and get a considerable amount of use and enjoyment out of your rig, your project may be worth it to you regardless of resale value.
