Abstract
An improved trailer structure constructed of light-weight material and especially adapted for hauling snowmobiles is described. An improved tongue structure, having a pair of opposed channels extending longitudinally, is shown arranged to cooperate with a hitch structure on a vehicle to allow an enhanced turning radius between the trailer and the vehicle. The improved tongue works in cooperation with an integrally formed tongue support channel for vertical and lateral support. An improved rear frame member protects associated lights and has a ramp member to protect the deck of the trailer when objects are slid onto the trailer from the rear. Side panel members and support beams support the trailer deck and can support associated stake holders for mounting auxiliary removable sides and ends on the trailer frame around the trailer deck. Each of the components is integrally formed by extruding a light-weight material, and cut to length for assembly.
