Abstract: A removable rear bed closure for a truck is disclosed as incorporating an upper roof portion and side walls that cooperatively define a rear opening with downwardly projecting hinge pillars of the side walls pivotally supporting associated rear doors for movement between open and closed positions about vertical axes. Each door has an upper end that seals with the upper roof portion and a lower end that seals with the truck bed in the door closed position. The hinge pillars are located laterally inward from truck bed side wall mounted taillights so as to not hide the taillights from view and the hinge pillars are located in longitudinal alignment with the bed side walls rearward thereof such that the rear opening has approximatey the same lateral width as the bed. Detachable securement of the closure side walls and the bed side walls to each other permits removal of the closure when desired.
