Are you wanting to trade it in or sell it out right?
Trade in you can expect about 24000-26000 depending on condition and the dealer. Assuming that your retail is 33000. That is about 70%, from retail.
Outright sell is a little trickier, there is so much competition for you so you have to give the buyer a reason to buy your camper over the dealer or the next guy. Typically price is going to determine that, but accessories & aftermarket add ons help too!
