Used generator questions

[Upinsmoke]

I believe I may be in the right church, but possibly the wrong pew. If so, please relocate it.

My cousin has an older (not antique) Class A which is junk, and he has removed the engine. The inside is in a shambles etc.

However, I believe it has a good generator on it. I should be able to get a look at it this coming week. He just wants it out of his lot and I'm thinking the generator must be worth something.

Are there RV salvage/junk yards? If so, any known good ones?

Thanks for any thoughts/suggestions!
