This is a very sturdy trailer dolly! It has and will continue to serve it's purpose very well. My only issue was there was no way to lock up the wheels. Handling a heavy load on a slight incline by yourself could really be an issue. For in a pinch, I added spring loaded slide bolts for both wheels, with holes in the rims to lock up the wheels by flipping up the levers. Now, without having to set the load down, in an emergency or just to hold the dolly with or without a load in place, they work GREAT!
