A pair of opposed A-frames are positioned uprightly on a flat bed chassis. A downwardly descending side leg on each side of each A-frame rests on an axially mounted beam. The beam is attached to the underside of the flat bed chassis and extends outwardly from a side surface of the flat bed trailer and is angled upwardly to support a bottom edge of a building material slab or sheet.
