The Trailer Valet XL is the toughest, most compact trailer dolly on the market today. It shares the same great features as it’s little brother, but also comes with a few upgrades. The XL moves most trailers up to 10,000lbs with just using a crank handle or an 18V drill. It features dual 9 inch tires that can handle up to 500lbs per tire, and our positraction technology for making tight turns. The automatic brake engages when the handle is released for superior safety. Making it ideal for boat, RV, construction, farm, horse, RTV, and flat bed trailers.
