Im looking for feedback from any other boaters out there that current use some kind of motorized boat dolly to move their boat around. I bought an old aircraft tug and had a friend modify it with a hitch ball. It has some center of gravity and traction problems, even on a flat driveway. I see plenty of tugs or dollys out there, Im just looking to see if anybody is using one of them successfully. One other thing, my tandem axle trailer is tough to move sideways, so please indicate if you have tandem or single axle.
