Abstract: A pickup truck tailgate construction is provided which enables the tailgate to be used either (1) in customary manner, with the bottom of the tailgate in hinged relation with the after end of the bed so that the tailgate can be pivoted between vertical closed position and horizontal open position or (2) in a modified fashion, in which the top of the tailgate is pivotally arranged so that the bottom of the tailgate can be positioned several inches rearwardly from the after end of the bed. The rectangular gap between the bottom of the tailgate and the adjacent after end of the bed and the triangular gaps between the opposite ends of the tailgate and the adjacent after ends of the side walls are spanned by correspondingly shaped mesh panels which allow free flow of air therethrough. Improved fuel efficiency and handling of the vehicle results from the aerodynamically enhanced construction.
