BACKGROUND OF THE INVENTION
The field of the invention is ATV Trailers.
Hunters and other outdoor enthusiasts frequently use all-terrain(ATV's) to travel into areas not accessible by other means of transportation (e.g. forested, rocky, steep areas.) Trailers pulled behind ATVs need to be capable of traversing rocky terrain with numerous obstacles.
This invention pertains to land vehicles generally, and more specifically to trailing vehicles configured for optimum performance with All-terrain vehicles (ATV) or off road vehicles. Most specifically, the preferred embodiment of the invention is a trailer for an ATV which traverses rough terrain.
Several ATV trailers are known in the prior are U.S. Pat. No. 5,645,292 to McWilliams et al. discloses an ATV trailer made from tubing, however, its suspension and wheel assembly is different from the present invention. U.S. Pat.
