This works great. We were able to maneuver two 7,500lb boats with two, let's say, medium-strength guys. It was a workout, but it worked. It was fun and easy to maneuver the boats with this. I recommend it.
I needed to get my 18-foot RV alongside my garage. I couldn't maneuver the RV with the truck attached. After some research, I came upon this dolly. I was able to move the RV (3500 pounds) by myself fairly easily. The assembly was a breeze, which is a plus, and this is built very sturdy. I highly recommend it.
I moved an 11000-pound camper 15 feet over gravel using mats under the dolly tires so they didn't sink. Worked great, I found stopping to be harder than starting because I was working on a slight decline so I used cinderblocks and placed a few feet in front of the tires to make sure I could stop it. The brake on the dolly worked well to hold it in place but not to stop momentum.
I don't have a easy trailer accessible driveway so this thing is king!!
Moved the 36' camper, 21' boat, and 17' boat in the building with this dolly. It made it easy to maneuver everything. I wish I bought one years ago.
