Do you still want the cheese, or is getting out of the trap your main concern? You may be able to get a bit more money out of a private sale, but the hassles will increase significantly. You will have to deal with tire kickers, with answering an unending stream of questions only to find out the potential buyer's payment plan is seeing if their lottery ticket is a winner.
You have to ask yourself why would a buyer travel to your location to view and potentially buy your fifth wheel over every other fifth wheel for sale within the same drive time radius? Since it is only two years old, I doubt superior condition would be the reason. Unless it is really unique, I doubt it will be because it is the specific rig someone has been searching for high and low. Therefore, the most likely reason would be price. You post suggests most potential buyers would have to drive a considerable distance so your price would probably have to be significantly lower than comparable rigs that are more centrally located. Personally, I would find a good consignment dealer, accept the fact I might be leaving some money on the table if the stars would have actually aligned had I chosen a private sale, and get on with more important things in life. Do you really want to become an RV dealer with only one rig in stock?
