Abstract
A unified hinge may comprise a hinge tube that is rigidly attached to a truck frame and a bed section of a truck bed and a tail section of the truck bed, each of the bed section and the tail section having opposing hinge barrels affixed thereto that concentrically align on the hinge tube. Similarly, a unified hinge may comprise one or more mounting barrels that are rigidly attached to a truck frame and a bed section of a truck bed and a tail section of the truck bed, each of the bed section and the tail section having opposing hinge barrels affixed thereto that concentrically align on the one or more mounting barrels; a hinge tube runs through the one or more mounting barrels and the opposing hinge barrels. The unified hinge allows the bed section and the tail section to independently pivot along the hinge tube.
