1972 Chevy Barth 22ft 454cu - $800 (Yoncalla)

"This motorhome has been in the family for over 20 years, I believe that last time it was started was in the early 90's. I think it was the Trani that went out but not 100% sure. Has many good parts that can be salvaged or may even be able to be fixed up if that's what you want to do, this is a very rare model and want to see it go to a good home rather than me just scrapping it. Text/Call 541-852-0926"

fixer-upper?
kinda looks beyond that.
But, for a mere $50K in work, it could lovely.
Port WS looks good.

Pull the windshields and talk to the scrap yard.
