Abstract
Abstract A trailer designed to be towed behind an automobile or the like and comprising a plurality of components including a base, side wall means surrounding the base, a top, a tow bar and a pair of spring loaded axis. The majority of the components which comprise the trailer are removably attached to the base or to one another such that each of the components may be disconnected from their assembled position and stored on the base of the trailer. The top and the base may be connected directly to each other to define a storage compartment in which the various components are placed such that the trailer may be shipped or transported by means other than towing.
