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.

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.

Methods of transporting a plurality of freight containers are disclosed, including stacking one or more containers on a transportation vehicle, where one or more of the stacked containers is a vertically collapsible container in a collapsed position, where at least one of the vertically collapsible containers includes: a frame assembly including: a plurality of rectangular frame members; a plurality of articulated vertical frame members disposed between the rectangular frame members; and where the articulated vertical frame members are positioned and arranged to retract to within the frame assembly; a lifting mechanism positioned and arranged to elevate the rectangular frame members from each other; and where the lifting mechanism is disposed between the uppermost rectangular frame member of the frame assembly and the lowermost rectangular frame member of the frame assembly.

An expandable multiple-axle trailer has a trailer wheel carriage with left and right sub-carriages having corresponding forward-extending sub-carriage extensions, the front ends of which define sub-carriage extension tongues laterally movable within slots in a first transverse trailer structure member while being constrained against longitudinal and vertical movement relative to the trailer, while intermediate regions of the sub-carriage extensions are correspondingly laterally movable within fulcrum slots in a second transverse trailer structure member aft of the first transverse member. The trailer wheel carriage incorporates actuation means for transitioning the trailer wheel carriage assembly between laterally-retracted and laterally-expanded configurations. The slots in the first and second transverse members define guide surfaces angularly oriented such that transitioning to the expanded configuration will alter the longitudinal pitch of the trailer wheel carriage to raise the rearmost axle relative to the forwardmost axle, and vice versa when transitioning to the retracted configuration.
