I ordered this in October before my 1300lb enclosed cargo trailer arrived. My business includes setting up at outdoor markets, simply parking the trailer between already set up stalls was not and option. Moreover, to help prevent theft, I always reverse the trailer in the parking stall I park it at, in addition to two wheel locks and a hitch lock. When I received this dolly I was pleased, and played around with moving my empty trailer. But I was still trepidatious about how it would hold up once my inventory arrived and was in the trailer. By the time is was fully loaded, my trailer weighed 3,500. I was DELIGHTED to discover that even when fully loaded, I could take my trailer out of its parking stall. I was further delighted to discover (after trial and error) that even on a slight gradient, I was able to lean backward and pull the entire trailer and turn it on a dime. Pushing, however, does NOT work against a gradient. This thing does indeed require some strength. I am 6 foot, 180 pounds and have been an athlete most of my life, so this tool works for me. The airless tires are awesome, it keeps the need to upkeep the dolly off of my plate. I only noticed just yesterday that some bolts fell out of the rim, and two more were loose and on their way out. I included a picture for reference. It's also clearly a durable dolly, as yesterday I accidentally ran it over with my trailer while.it was fully loaded and it shows no signs of bending or displacedment. Besides the bolts, I am VERY VERY pleased with this product, I COULD NOT RUN MY BUSINESS WITHOUT IT!
