A rotatable trailer bed includes a frame, a trailer bed, a turntable swivel assembly, and a plurality of swivel casters. The frame includes a bed section, a hitch section, and two wheel sets. The hitch section is adjacently connected a front end of the bed section. The two wheel sets is rotatably mounted to the bed section. The plurality of swivel casters is mounted to the bed section is perimetrically positioned around the bed section. The trailer bed is rotatably mounted to the bed section through the turntable swivel assembly as the plurality of swivel casters maintain the balance and level of the trailer bed.

A tailgate system, comprising: (i) a tailgate door configured to pivotally engage a rear cargo area of a body of a vehicle in between a closed position and an open position; and (ii) a bed extension pivotally engaged to the tailgate door and configured to pivot from a closed position to one or more open positions, wherein the bed extension includes a plurality of removable panels.

An automated cargo vehicle ramp deployment system includes a controller and a power source connected thereto, a ramp located at the existing cargo vehicle, a first automated ramp displacement mechanism for configured to selectively displace the ramp from a first position to a second position defined along a perimeter of the existing cargo vehicle while the ramp is maintained at a vertically oriented position, a second automated ramp displacement mechanism for configured to selectively displace the ramp from one of the first position and the second position to a third position, and a third automated ramp displacement mechanism for selectively adjusting a longitudinal length of the ramp while the ramp is statically disposed at a third position.

A waste removal system with a trailer for the storage of materials such as waste or rubble, wherein said trailer has a front wall a rear wall and plurality of side walls with an extended slope on at least one of said walls to increase the volume capacity therein. The trailer may additionally contain a slanted access door or ramp which alternatively raises and lowers, allowing for ease of ingress and egress of the trailer volume. The waste removal system may additionally include a transport vehicle with a grappler mounted at a distal end of a boom, wherein said grappler grasps waste and deposits said waste into the previously-mentioned trailer for transport to and from a desired location.

A tonneau cover system for a vehicle includes at least two panels configured to collaboratively form a container. The at least two panels extend laterally when connected to a tonneau of the vehicle. A first panel is movable between an open position and a closed position to gain access to an interior space defined by the container. In the closed position, the first panel extends parallel to a floor of the tonneau. A second panel is selectively placed in a cover or a storage position. In the cover position, the second panel extends parallel to the floor to collaboratively cover at least part of the tonneau. In the storage position, the second panel extends perpendicular to the first panel in the closed position. The first and second panels collaboratively form the container when the first panel is in the closed position and the second panel is in the storage position.

A ramp door closure apparatus is provided for recreational vehicles, having a recessed linear actuator both draw a cable from a mounting bracket on the ramp door adjacent to the RV opening, to raise and lower the ramp door, and then cam a locking pin fixed to the ramp door into a seal tight position after the ramp door is raised. Upon release of the locking pin from the cam when opening the door, an initial push is provided to facilitate downward rotation of the ramp door. The linear actuator is selectively detachable from the cable so as to allow manual raising and lowering of the ramp door from within the RV, by means of releasable pins accessed in the mounting structure.

A cargo bed system of a vehicle includes a bed floor assembly of a cargo bed. The bed floor assembly is configured to transition back-and-forth between a standard bed position and an extended bed position. A ramp assembly moves together with the bed floor assembly back-and-forth between the standard bed position and the extended bed position. The ramp assembly is configured to move back-and-forth between a stowed position and a deployed position.

A tailgate system for a vehicle having a body defining a rear cargo area and an opening, the tailgate system comprising: (a) a tailgate door adapted to pivotally engage the rear cargo area in a first direction between a closed position and an open position; (b) a bed extension pivotally engaged to the tailgate door; and (c) one or more ramps, wherein the bed extension is pivotally engaged to the tailgate door and adapted to pivot from a closed position to one or more open positions; and wherein the one or more ramps removably attach to the bed extension.

A ramp system for transporting a vehicle between a trailer and a truck includes a first ramp having a first end extending into the trailer and a second end configured to be detachably secured to a horizontal rail of the trailer, a second ramp that can be pivotally secured to the first ramp, and a hinge assembly including a first ramp knuckle disposed on the first ramp, a second ramp knuckle disposed on the second ramp, and a hinge pin configured to be disposed through a first ramp bore and a second ramp bore to pivotally secure the second ramp to the first ramp. The second ramp can pivot via the hinge assembly between an open and a stowed position. The ramp system can include an inner ramp configured to slidingly engage with the second ramp between a retracted position and an extended position.

In one embodiment, a truck trailer has a cargo container that defines a cargo area therein. The trailer has a rear cargo lift having a platform disposed within the cargo area at a rear end of the trailer. The platform is vertically movable between a floor of the trailer and a first elevation that is above the floor. The trailer has an upper cargo deck supported within a portion of the cargo area that is between the rear lift and a front end of the trailer. The upper cargo deck divides the portion of the cargo area into upper and lower areas. The upper cargo deck can align with the rear cargo lift at the first elevation so as to receive cargo into the upper area, and translate the cargo to a second elevation that is above the first elevation so as to receive cargo in the lower area.
