We have a Kar Kaddy SS by Demco and Love it. It follows like a champ. We have never had a problem at a campground. It is very light so if you want to disconnect its very easy even my wife can move it and we are not "spring chickens". After practice you can connect or disconnect in about 4-5 minutes. The part I like is you can tow any car any time. No special modifications on a not so new car. I think you can rent one from U-Haul to try it out, even though they have basic model. Good Luck!
