Provided is a rear axle movement device for a truck with a lowerable bed, comprising: a front axle, a driver's cab, a rear axle, a cargo container, a sub-frame, a first lifting device, a second lifting device, a first guiding device, a second guiding device, and an electric motor. According to the present invention, the rear axle movement device utilizes a chain and a sprocket.

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.

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.
