Abstract
Abstract A rotating and tilting double bed trailer for use with lightweight off-the-road vehicles, such as snowmobiles, motorcycles, all terrain wheeled vehicles and the like. The trailer has a double bed that is capable of full circle rotation, and each bed tilts individually to load or unload an off-the-road vehicle. A positive locking of the tiltable beds in either a forward position or a reversed position is accomplished by a locking turntable plate on which the tiltable beds are mounted. The tiltable beds have fold-up front and rear bed extensions hinged to their ends to help contain items carried on the bed, and to serve as a ramp means during loading and unloading of the trailer.
