A tarpaulin support for a tarpaulin system that turns a flat bed trailer into a fully covered van and back again into an open flat bed trailer. The support is comprised of an upper tubular bow of inverted U-shape to extend laterally across a trailer and, each side of the bow having a lateral, downwardly extending tubular arm. A structural member is secured to the tubular bow along its outer periphery and extends below the free ends of the arms of the tubular bow, the structural member provided with structure to secure thereto peripheral portions of tarpaulin sections for covering the trailer. A pair of planar bases are associated with the bow, one on each side and, each base having a roller arrangement secured thereto for sliding movement on a corresponding rail mounted on a corresponding side of the flat bed. Corrugated plate having vertically formed corrugations is secured to each structural member below the corresponding arm and its associated base. The corrugated plates have sufficient structural strength to support the tubular bow and its structural member and associated tarpaulin sections when in position. The overall thickness of the corrugated plate between opposite surfaces is less than that of the tubular bow.
