I bought one at my neighbours garage sale. I was skeptical as to how well it would work on my rural gravel parking lot. Using the TV to park my boler
1700 was really a pain though so I decided to try it. My parking lot is relatively soft sand gravel that is uneven and sloping down hill from the trailers "spot". No brakes
either. So the next time we came home I just drove into the yard like I was not towing a trailer and parked the truck in its spot nose in. Then my wife and I unhitched the trailer and slipped in the two wheel dolly. We pushed it backwards, uphill, and turned it around 180 degrees before easily pushing it backwards into its designated place. We could not believe how easy it was and that we did not do it sooner.
