You should fill out your profile so that we know what part of the country you are in.
For instance, I know of a place in San Antonio, TX that has dozens of refrigerators, water heaters, etc. ripped out of salvage RVs just sitting out in the weather. Best I can tell though, you would have to go pick one out and probably remove it yourself. I bought a couple of small parts there and they told me to go get 'em myself. Prices were right, though.
