"You can quickly and easily move your trailers with the Tow Tuff Heavy-Duty Adjustable Trailer Dolly with Caster. This adjustable trailer dolly is the perfect way to move your trailer into storage, through tight areas, and in spaces that you can't drive it. The 1000-lb. capacity of this dolly allows you to easily move a wide variety of trailers. The dolly features two 16"" flat-free tires and one 10"" swivel caster to provide smooth-rolling and easy steering. The back caster even helps to keep the load of the trailer from putting too much weight on you. This boat dolly accommodates many different sized trailers with an adjustable height, allowing you to go from 21"" to 33"" to meet your trailer height. The dolly is constructed of a solid steel frame with a hammer-tone, powder-coat finish for a durable dolly that resists corrosion for a long-lasting product. The 30"" wheelbase adds stability to your trailer dolly as you turn, giving you a safe dolly. Additional leverage with the 40"" handle makes it even more effortless to move trailers. This Tow Tuff dolly works with 2"" coupler or larger.
