Disclosed herein is a retractable cargo box assembly for a cargo bed of a vehicle. The retractable cargo box assembly includes a cargo box. The cargo box includes a base extending laterally between a first side and a second side, and extending longitudinally between a front end and a rear end. A linear wheel assembly is mounted to the base. The linear wheel assembly includes a plurality of rollers aligned in a linear arrangement between the front end and the rear end of the base. The rollers are configured to rotatably support the cargo box on the cargo bed of the vehicle between a retracted position and an extended position.

A replacement tailgate for the purpose of elongating the pick up truck may be installed on a truck bed wherein the replacement tailgate can be unfolded in order to elongate a length of the truck bed. The replacement tailgate may have front and rear shells that are used to support objects placed in the truck bed as well as act as the new tailgate when the truck bed length is elongated. Various panels may be unfolded in order to trap objects within the truck bed when the replacement tailgate is unfolded in order to elongate the truck bed length.

A system for truck bed extension that includes: a truck bed, where the truck bed includes a first tail gate; an extension portion of the truck bed, where the extension portion includes a first position and a second position, wherein the first position is retained in the truck bed behind the first tail gate and the second position extends beyond the first tail gate extending the length of the truck bed; and a second tail gate on the extension portion, where the second tailgate is available when the extension portion is in the second position. The system for truck bed extension may also include a locking mechanism for the extension portion to lock the extension portion in either the first position or second position. The extension portion may extend at more than one length and preferably extends up to 4 feet beyond the first tail gate.

A telescoping truck bed shell is disclosed herein. The truck bed shell is capable of being retracted so that the user can have full access to the truck bed and also extended so that the user can have a protected volume at the truck bed in order to store things. The telescoping truck bed has traversable frames and a traversable cover wherein the frames and cover may be traversed between extended and retracted positions depending on whether the truck bed shell is being deployed or stored.

The foldable truck bed extension deck and ramp assembly are mountable in a short-box pickup truck. The bed extension deck and ramp assembly have a comparable length to a full-size pickup truck box when deployed for use, and are jointly foldable to fit into a short-bed pickup truck with its tailgate closed when not used. The bed extension deck has a strong upper surface to resist deformation in rough use. The ramp member can be deployed with its front end matching the surface of the extension deck so that a vehicle can be driven along the ramp member and onto the deck surface without encountering any transition step.
