Abstract: A cargo cover apparatus configured to selectively enclose a space above an upper surface of a cargo support bed may include at least one bulkhead mountable on the bed toward one said end of the bed, and a cover assembly mountable on the bed in a position between the forward and rearward ends of the bed and toward the at least one bulkhead. The cover assembly has a front end and a rear end, with one of the ends of the cover assembly being orientable toward the at least one bulkhead, and may be extendable and retractable to change a distance between the front end and the rear end of the cover assembly along the longitudinal axis of the bed. The apparatus also include a securing assembly configured to secure one of the ends of the cover assembly to the at least one bulkhead.
