I’m sorry to hear that. Now is historically a slow time for RV sales, but if you start getting ready now sales typically start kicking up in a few weeks in February. If you have the time/patience I would suggest selling via classified listings, such as RVT.com, RVTrader, or Facebook Marketplace to get the most money out of it. Otherwise, you could sell it to a dealership or through consignment, which might be your quickest option but you’ll typically get less for it.

Good luck!
