There are a LOT of scams on Craigslist. I'd recommend a site like RVTrader.com where you will find legitimate sellers, both individuals and dealers.
And, as I've found over the years, don't automatically assume that all private owners are honest and have their units priced well, and by the same token don't automatically assume that all dealers are dishonest and have their units overpriced.
At least you can go online and read reviews about the dealers .... the individuals, not so much.
Just do your due diligence, and best of luck to you in your search.
. . . never confuse education with intelligence, nor motion with progress
