Buying an RV through a dealer or private seller?

I’ll buy from either one, but I prefer private sellers. I think I can tell how honest someone is pretty quickly if I talk to them for a bit. And I check the unit pretty thoroughly. If I have any doubts the sale’s contingent on my having it checked by a tech that I trust. I start out with local sources like the newspaper and local dealers. Then I’ll expand if I don’t find what I’m looking for, but I’ve never had to do that.
