I sold two RV's on Craigslist and both sold for my asking price and with very little hassle. The first one sold to the first person to look at it and the second one sold to the second person to look at it.
If you plan to sell your RV then price it according to what you are willing to accept, plus a few thousand negotiating money.
From the questions I received on my first sale, I made adjustments to my second listing.
Obviously you want to clean up everything and make any repairs that are necessary. You also want to take very good pictures of all aspects of your coach. Craigslist allows you to post 24 pictures so do it.
I planned to "sell" my RV rather than give it away so I listed mine at the upper end of the retail value and was not interested in any offers from dealers.
One of the most asked questions on my first coach was about the tires so on my second RV I added an extra $3000 to my asking price and offered the new buyer their choice of new tires that I would have installed for them. Turns out my buyer picked Michelin snow tires since they planned on using the coach to go to ski resort areas. Living in Florida I had to order the tires online which was no big deal. I also offered to pay for two nights at a local RV park so that they could become acquainted with all of the systems. $150 well spent. I got my FULL asking price from the buyer.
In my listing, I also made it a point to mention all of the extras that came with my coach from the factory as well as ALL of the items that were included with the sale. As far as I am concerned you cannot tell too much information about your coach. Remember what made you pick that coach when you bought it and mention it in your listing.
There is a big difference between pricing your coach so low that you are giving it away and taking the time and effort to actually sell your coach. The decision is yours as to how much effort you want to invest. My approach netted me thousands over what similar coach had sold for.
