My 13 ft travel was parked in my back yard in grass in a hole so I wasn't expecting this mover to do much good. I hooked it up and hit the forward button and it slowly dug a hole while going nowhere fast. Rather than give up I jacked the trailer back up and slid a 6 ft long 2 x 6 under the mover, set it back down and hit the forward button and away we went. (for six feet anyway). I used a couple of 2 x 6 planks under the wheel, moving each plank in front of the other while moving 6 feet each time to pull that trailer across my backyard in soft grass until I could get it to the side of the house to hook up to my pickup. Long story short. This thing works and it has PLENTY of power for moving my 13 ft travel trailer even when it had to be pulled up a slight incline as it was sitting down in a hole. The tongue of my trailer is heavy which helped it get traction on the 2 x 6 boards. The single bolt mounting system is in need of a redesign, which I intend to fix. It doesn't support the dolly as it should, but the mover itself made my day a heck of a lot easier getting that trailer out of my back yard. I recommend this product and it's well worth the selling price.
