Where's a few good sites to place a camper for sale?

Agree on Craigslist and definitely agree on the Bozos. Advantages of CL are that you can reach multiple areas and it's free. The downside are the goobers that have nothing to do with their day but hang on CL and be a nuisance. Some will suggest corresponding with their/your personal email or phone. DON'T! Go through CL email only until you feel very, very sure that it's a legitimately interested buyer. I've never used Ebay. Another option is just your local newspaper. We sold both our HTT and just yesterday sold our Rocky on CL. Just be cautious with personal info and definitely nothing financially connected.
