Hope you don't mind the PM, but you seem to know more than a little about Travcos, and they're not really expo vehicles...
There's a guy been advertising a "70's 21' travco" locally. Say's it's all there but doesn't run. Not much more info.
I realize that it would probably be more project than I can sell my wife on, but he's only asking $700.
What's your gut tell you?
