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.

A system for assembling a door to a vehicle container having first and second pillars includes a first base adapted for connection to a top portion of the first pillar, a second base adapted for connection to a top portion of the second pillar, and a hinge assembly adapted for pivotally connecting the door to the vehicle container. The hinge assembly is adapted to be removably connected to the first and second bases and to the door. The hinge assembly is selected from first and second hinge assemblies. When the first hinge assembly pivotally connects the door to the vehicle container, the door has a first pivoting configuration. When the second hinge assembly pivotally connects the door to the vehicle container, the door has a second pivoting configuration being different from the first pivoting configuration. A vehicle container and a door for a vehicle container are also encompassed.

A tailgate apparatus for a dump body is described herein. The dump body includes a floor, a front wall coupled to and extending upwardly from the floor and two opposing side walls coupled to and extending upwardly from the floor. Each side wall is coupled to the front wall. The two side walls define an opening at a rear end of the floor. The tailgate apparatus includes a tailgate sized to cover the opening and two opposed side arms extending from the tailgate towards the front wall. Each side arm is pivotally coupled to a respective one of the side walls. The tailgate apparatus also includes a pair of linkages for linking the side arms to the side walls. The linkages enable the tailgate to pivot between a closed position where the tailgate covers the opening and an open position where the tailgate is positioned closer to the front wall than the opening.

A system for assembling a door to a vehicle container having first and second pillars includes a first base adapted for connection to a top portion of the first pillar, a second base adapted for connection to a top portion of the second pillar, and a hinge assembly adapted for pivotally connecting the door to the vehicle container. The hinge assembly is adapted to be removably connected to the first and second bases and to the door. The hinge assembly is selected from first and second hinge assemblies.

When the second hinge assembly pivotally connects the door to the vehicle container, the door has a second pivoting configuration being different from the first pivoting configuration. A vehicle container and a door for a vehicle container are also encompassed.

A vehicle container has a vehicle container body, a door pivotally connected to the vehicle container body, the door defining at least one recess, and a door latch system for locking the door in a closed position. The door latch system has an extendible and retractable actuator pivotally connected to the vehicle container body, a linkage assembly operatively connected to the actuator, a rod operatively connected to the linkage assembly, the rod being pivotable about an axis upon extension and retraction of the actuator, at least one hook connected to the rod, the at least one hook being received and withdrawn from the at least one recess of the door by pivoting the rod about the axis, and at least one pin removably fastened to the door and extending in the at least one recess, the at least one pin being selectively movable relative to the door.

A vehicle container has a vehicle container body, a door pivotally connected to the vehicle container body, the door defining at least one recess, and a door latch system for locking the door in a closed position.
