* We compare like with like: the dealer's total with fees if it shows one, otherwise the advertised price. Taxes, title and registration are never included, so ask for the out-the-door price (the full amount you would pay). Real Price is the price in the middle of the listings we compared. It is not a sale price. A price drop means the advertised price went down.

Prices shown are advertised prices. We compare like with like: the dealer's total with fees if it shows one, otherwise the advertised price. Taxes, title and registration are never included, so ask for the out-the-door price (the full amount you would pay). We don't show or store dealer photos. The “See photos” button opens the dealer's own page for that RV. Used units are never part of a Real Price.
