Abstract
A trailer includes a trailer frame using suspension cables supported from vertically extending towers on opposite sides of the trailer frame and connected to distal ends of the trailer frame for supporting distal portions of the trailer frame. The trailer bed frame comprises a plurality of folding frame sections which can be unfolded into planar alignment to form the trailer frame and folded into an overlapping or stacked alignment for storage. Left and right wheels are rotatably mounted on left and right suspensions which are removably securable to left and right sides of the trailer frame. The suspensions may comprise quarter elliptical leaf spring suspensions.
