A system for covering a vehicle platform defining opposed ends. End elements are mountable to the vehicle platform adjacent its ends and a tarpaulin attachment element extends therebetween. A tarpaulin defines a tarpaulin movable end and a tarpaulin fixed portion extending in a parallel and spaced apart relationship relative to each other, the tarpaulin fixed portion being secured to the tarpaulin attachment element. An end rod is mounted to the tarpaulin adjacent the tarpaulin movable end and a support member is mounted to the tarpaulin a location intermediate the tarpaulin fixed portion and movable end. An actuator moves the tarpaulin between tarpaulin retracted and extended configurations. In the tarpaulin retracted configuration, at least part of the tarpaulin is wound around the end rod. In the tarpaulin extended configuration, the tarpaulin is unwound from the end rod and extends along the end elements, the support member abutting against the end elements.
