I towed with a dolly for a while, before going to 4 down towing. Like most, I much prefer 4 down towing, but if I ever go back to a tow dolly (won't rule it out), it will be with the same one I had before, what is IMO the best dolly you can get (and only one I'd ever own): The
ACME EZE tow dolly.
You just can't beat it, IMO. Lightest dolly made, at only 330 lbs, so easier to move around by hand than almost any other dolly. The thing is so low profile, you can store it almost completely under the back of your Motorhome, so it uses very little space when parked (uses less space than even the much more expensive folding Demco Kar Kaddy ). Detachable ramps eliminate risk of ramps hitting bottom of car. Design pretty much guarantees you can take some pretty tight turns, and its almost impossible for car to touch dolly's fenders (I personally tested, verified this on mine years ago). Its light weight means you can tow a pretty heavy vehicle and still stay under the 5k (total) limit many Motorhome hitch receivers have. Oh, and comes with hydraulic activated disk brakes, and LED lighting.
No, I have zero affiliation with the company that makes it. I'm just one that used to own one, and knowing what I know now and what I researched back then.....I know I made the right choice then, and would make the same choice again if I ever decide to go back to dolly towing.
