You have a few options. You could call around to some local dealers and see what they will offer you for it, which is certainly the quickest way out, but may not give you the most cash. You could look into consigning it somewhere, which takes away a lot of the headaches from selling it (they advertise it for you and have knowledgeable salespeople who will try to sell it to interested parties), or you could try to sell it yourself. You will probably get the most for it by selling it yourself, but it will most likely take a bit longer. Some tips for selling it yourself:
-Post it in multiple places, such as RV Forums, RTV.com, RVTrader.com, craigslist.com, racingjunk.com, your local classifieds, etc.
-Post plenty of well-lit pictures of both the inside and the outside of your coach.
-Make sure you have your RV CLEAN and clutter-free before you photograph it.
-Post as much relevant info as you can about it, including the mileage (don't just say "low mileage")
-Post your phone number, but do it using a mixture of numbers and letters, so that spam-bots can't call you. Like this "My phone number is 91six 4five2 seven33two"
-Be realistic on the price, take into account the age and condition of your RV, and look online for the exact same model, see what they are selling for, and price yours just slightly lower.
