well I got a neighbor in the scrap biz who gets rvs given to him, he peels them for the metal (frame), aluminum (skin) and copper (wiring+gas lines), and burns the rest. He tossed out a LOT of good dometic fridges, stoves, heeaters etc
I have been taking stuff that has demonstrable life left, any boards, brake parts, drums, and few appliances.
we got sooo many 70's 80's class C's around here - on dodge, ford and gm van chassis with engines from mopar 318s up to 460's. and a ton of gm 400s (Im betting the 406 class racers didnt consider rvs as a source for 511 blocks) and the owners want like 500-1000 for them. if they are not moldy oldies with some roof integrity, I am looking at them. I figure new floor covering, wall covering, reseal it, freshen the engine, perhaps a reman tranny (those old 400s, c6s and 727s are a dime a dozen) and I might be able to hit a price and net 500-1000 per. at the very least I am doing a lot of rv wiring this summer....
