I used Uhaul dolly's for over 6000 miles towing a Saab behind a 37 footer. I could load/unload in minutes. Towed well, lights worked. Used Brake Buddy as aux brake system. Check the straps at every stop. Had one dolly that had a tweaked axle, i think, as it wore out inside edge of a set of tires in just a few hundred miles. Uhaul changed tires at a campground, no problem.
