Abstract

A trailer has a three-section flat bed in which the front and rear sections fold onto the middle section. The trailer has an airbag suspension system and one wheel on each side. When the airbags are deflated, the entire flat bed forms a ramp for loading and unloading. When the airbags are deflated and the flat bed is folded, the trailer can be stored vertically while resting on its wheels.
