Abstract: A tarp assembly is provided for a pick-up truck, and includes a pair of elongated rails mounted to the side walls of the truck along the truck bed. The first rail includes a rotatable shaft with a crank assembly controlling the rotation of the shaft. A tarp is movable between a storage position within the first rail and a use position extending over the rails and over cargo contained in the bed of the truck. A hook on the free side of the tarp secures the tarp to the second rail in the use position.
