Works to manipulate tandem axle boat trailer around garage. As others mentioned, the weight rating is a bit liberal. I have to go slow and use caution to position trailer or unit either looses traction or lifts a wheel. Luckily, my drive and garage are flat and on plane to each other.

I thought that my wiring was incorrect but when I called the help line they told me that I needed to turn on the switch at the battery charge indicator. I didn't even know the switch was there. It is a little gray rubber-covered push switch at the back end of the battery indicator, right above the throttle (see picture). Once I pushed that switch, the dolly worked great. It would have been nice to have had that little piece of information in the instructions!!

I have a 3200 lb 3-horse trailer with a 540 lb tongue weight. My trailer is over 23 feet long and my driveway is only 30 feet wide, I can't turn the trailer around while it's hooked to my truck so I have to unhook from the truck and turn it 180 degrees to get it pointed in the right direction to go back down the driveway. That's why I bought this. I was a little worried because it's a big warmblood trailer at the upper end of the capacity of this machine, but it handles it fine.

I've used it probably five or six times in the last couple of months and it's been stored in a shed that whole time when not in use. Even though I haven't charged it, the battery is still showing full.

The dolly works well, best advice is to GO SLOW. Just take your time and you won't have any issues. If you try to go max speed you will run into all the same problems that people have written about on here.

Make sure that you keep your trailer wheel close to the ground because if you try to go too fast, the dolly will have a tendency to tip forward and drop the trailer down. Having the wheel of the trailer close to the ground keeps the dolly from tipping too far. Also, keep some downward pressure on the handle and, again, GO SLOW, that will also help to keep it from tipping.

If you have a heavy trailer, don't make sharp turns. Better to do a 4 point turn at a more shallow angle than try to turn it all at once. If you try to do a 90 degree turn, it's likely one of the wheels of the dolly will come off the ground and you will lose traction, the dolly will lift on one side.

I have a cement driveway so I can't speak to how this will work on grass or gravel, but I've seen other comments on here saying that you would need to change to tractor-type tires, and that makes sense.

This machine does not have a brake function, so be mindful of that if you are using it on a slope. I would not count on this being able to stop a runaway trailer on a steep slope. I have a tiny slope on my driveway and it's no problem.

This is a great value, plenty powerful, you won't find anything else out there that's close to this price that will do the job that this machine does. You can get better machines but they will be twice the price.

I did have an issue with the differential leaking but customer service was extremely helpful and responsive, and ultimately ended up shipping me a new unit. They were great.

Summary: Turn the switch on at the battery AND at the battery charge indicator, GO SLOW, don't turn too sharp, keep some downward pressure on the handle, and keep your trailer wheel close to the ground. If you work within the limits of the machine, you shouldn't have any problems.

So overall I am extremely pleased with this purchase. Great value, great customer service, GREAT machine if used within its limits.

I love this dolly. After years of pushing my trailers down the side of my house and throwing my back out I decided to bite the bullet and purchase it. It is so easy to maneuver my boat with out any of the stress of backing it down with my truck. This dolly saved my back and maybe my marriage. lol

Works exactly as expected. Moves my 18 Ft car hauler with ease.

It pretty much needs a front legs front wheels I mean
