I don't know the answer but I can tell you my experience. The tow car I previously owned was advertised on Craigslist as a tow car. When I went to see it at the seller's house, there were people standing in line right behind me waiting to see it, and more coming. So I had to make an instant decision if I really wanted it. When I decided to sell it, I also advertised it on Craigslist as a tow car. I got several calls from RVers, but eventually sold it to a non-RVer since he was one of the first to call...and didn't care that it had a base plate on it.
But I did all this in the Phoenix Craigslist, an area where there are lots of snowbirds. So maybe it was a relatively easy sell.
