Camping World accepts RVs on consignment -
See here.
Can be beneficial since there is no hassle for you and they have the benefit of nationwide marketing and sales support. That is not free and should not be.
May be a solution for the OP since he is not ready to make a purchase at this moment. I have sold 2 RVs on Craigslist along with other items, but make no mistake I am no fan of CL. Too much risk of ciminals and other low-lifes there and in addition, the people looking to buy there usually want to low-ball on price.
