Trailer Valet TVXL25 XL Trailer Dolly - 2-5/16" Ball

I used this item on a 21 foot camper that weighs roughly 3,800lbs. Used it on a cement driveway with a slight slope. I used it with the manual crank. I watched the manufacturers video on connecting and using and it worked as advertised.On a cement and asphalt surface it works great and there were no traction issues. I was able to maneuver the camper with ease. I tried the unit at my storage site first and on gravel it would not work. I needed to put down wood running boards for traction.I achieved the precision positioning that I desired in a tight spaced driveway. I recommend this unit if you have a heavy camper or trailer to move on a hard surface.

came very quickly and is a very nice unit works well but I had to put plywood down to move travel trailer on grass

The Trailer Valet XL works, BUT beware - it is not as easy or intuitive as the company's videos make it out. Firstly, read the manual! Don't feel you can just use it out of the box based on intuition or because you're naturally "handy". Secondly, make sure the ball is TIGHT into your hitch. Lastly, be very wary of using a drill to power it, especially with a large, heavy trailer on anything but perfectly flat ground (I use it on a 25' Airstream that is somewhere north of 6500 lbs). I saw how easy it looked in the videos but found that in actuality I came close to breaking my wrist from the torque of the drill (a Milwaukee M18 set to low speed). Feathering the drill is critical to avoid injury. I put the drill away and am just using the included manual crank handle, which was not my plan when I bought it. Also make sure to understand how the brake works - I learned that failing to set the brake before letting go of the drill (or crank) can release a fair amount of energy causing it to spin, with a potential for injury. Worth the money, but be prepared - be confident in your physical strength and ability. This is not a light device either.

It’s a piece of junk

I am using this on a flat concrete floor. I use it to move a 30’, approximately 7500 lb travel trailer around. It’s far more convenient to use than fully hitching it up to a truck. I can see how some may have difficulty moving trailers on inclines or rough terrain. In that case I would probably use plywood for the dolly and wheels with chocks to prevent rollback. It works great overall.
