Start the bidding at 1 cent with no reserve. That will surely move your RV. People sometimes bid only on the ones with no reserve. And people (myself included) search *only* on things that have at least one bid.
If it's not moving at the reserve price, it's because the reserve is set to high, right?
You can always un-list it if you want, but you'll be mising out on the last minute bids that often double the offer. Some people
bid *only* at the last minute.
