Selling privately is a very chancy business. Somebody who thinks your rig is just perfect may happen along quite quickly, but many people have had their RV For Sale signs out for more than a year. I know two people who have yet to find a buyer and they have tried consignments, local ads, online ads (e.g. RVClassified.com) and signs in the front lawn - nothing has worked. Not even major price reductions. And both rigs are in nice shape too.
Some folks are afraid to buy privately because they worry about problems and after sale service. They seem to think they need an Rv dealer to back up the sale.
