When you decide on a price add $5,000.00 to it and put it on Craigslist in the RV section. After a week lower it by $1000.00 and so on. Stop lowering it at the price you started with and wait. It will sell, but the 2WD will limit your customers. Put your phone number in the ad and post all the pics that you can.
Parking it in high traffic locations during the day works also. Places like Tractor Supply, Lowes, Home Depot, and Harbor Freight work well and they won't hassle you. Bring it home at night. Move it around if it doesn't get a hit.
