Suggestions on a used Class C for a family of 4

I'd check CL... but be advised that it is crawling with scammers so keep your BS detector on its maximum setting, use a disposable E-mail address and for a phone number, either use Google Voice or buy yourself a burner phone, some number you can easily toss if you find yourself on the line with a criminal.

I also keep my eyes on rvtrader, but again, keep the BS detector on ultra-sensitive.
