I use one and it works quite well. My TT is only 24' and under 5,000lbs however I do manage to get it up a slight incline. It's slow moving, even with the drill attachment but I guess that's a good thing. It's also compact so it can travel with you. That being said, it won't work on grass or slick/muddy conditions. BTW... the design and construction of the Valet is impressive.
