I've sold 3 motorhomes myself. Try craiglist, RVtrader and ebay. I had calls from all listings, so hard to tell one is better then the other. When I listed, I listed at a fair price, lots of details, and lots of pictures. One I sold in a couple of days, another was a week or so, and the other in about a month. Make sure you ONLY do a bank wire transfer. Cashier checks are no guarantee, they can be cancelled. You'll get phone calls from companies claiming they sell 85% of the listing if you give it to them. Several of them I heard from, I had never heard of.
