A system including a container having a door pivotably coupled to the container that is movable between a first position and a second position. A locking assembly is coupled with the container and includes a first shaft and a second shaft generally parallel with and spaced apart from the first shaft, and an over center linkage extending between a respective first pivotal connection between the over center linkage and the first shaft and a respective second pivotal connection between the over center linkage and the second shaft. Further, the locking assembly includes at least one latch coupled with the second shaft and movable between an unlatched position and a latched position. The over center linkage is movable, when the door is at the second position, over center to a state at which the latch is in the latched position and the door is biased toward the second position.

A cargo bay accessory for inserting into a cargo bay of a truck, the cargo bay accessory having opposing stepped side walls forming horizontal support surfaces at different elevations, wherein the support surfaces on one side are at the same elevation as the support surfaces on the opposite side, and wherein the lower support surfaces are laterally spaced closer together than higher support surfaces.

A tiltable hauling device includes a frame assembly that supports a ramp. The frame assembly includes a pivot bracket with a first pivot guide and a second pivot guide. The ramp includes a first hinge pin and a second hinge pin. A tilt assembly includes a pivot guide that is configured to selectively engage the first hinge pin and the second hinge pin to optionally restrain and permit movement of the first hinge pin and the second hinge pin within the respective first pivot guide and the second pivot guide to enable tilting of the rack in two directions respectively about the first hinge pin and the second hinge pin.

An apparatus for remotely locking a container includes a vehicle having a main frame and a tipper frame hingedly connected to the main frame, at least one of the main frame and tipper frame being configured to receive and support a container thereon; an actuator assembly for pivoting the tipper frame relative the main frame between a reclined, container loading and transport position and an inclined, dumping position; a container configured for receipt, transport and dumping of material, including a box defining a rear opening, and having a door hingedly connected with the container box to swing between an open, material dumping position and a closed position covering and sealing shut the rear opening; at least one lock mechanism connected to at least one of the box and the door; a locking assembly connected to the container; and, an actuator assembly connected to the tipper frame and physically separate from the locking assembly, and when the container is juxtaposed atop the tipper frame said tipper frame is in the transport position, the actuator assembly is operable upon actuation to engage with and cause the locking assembly to engage with the at least one lock mechanism to pull the door tightly against the box and seal closed the opening.

An apparatus and method for quickly mounting an accessory in the cargo bay of a truck is disclosed. Quick-mount devices lock onto tailgate pivot members of the cargo bay of the truck. The quick-mount devices may utilize locking tubes that extend laterally to engage the tailgate pivot members and secure the accessory, or retract laterally to release the tailgate pivot members and remove the accessory. In one embodiment the accessory is a dump insert. In a further embodiment the dump insert has stepped walls.
