Abstract: A generally horizontal load bed is provided including a longitudinal marginal edge and a plurality of cantilever support arms are spaced along the marginal edge of the support bed and pivotally supported therefrom at one set of corresponding ends of the arms for angular displacement of the arms relative to said load bed about upstanding axes for swinging between extended positions with the other set of corresponding ends of the arms projecting outwardly from the load bed marginal edge and folded positions with the arms generally paralleling the load bed marginal edge. An elongated extension panel assembly is provided and parallels the load bed marginal edge and overlies and is supported from the support arms.

Abstract: An extendible tailgate assembly for a load carrying vehicle has a tailgate pivotally mounted on the main frame of the vehicle and slidably supporting an extendible member arranged for reciprocating movement relative to the tailgate and increasing and decreasing the extent of the tailgate assembly. The extendible member is guided relative to the tailgate by a linkage which assures parallel movement of the extendible member relative to the tailgate.
