A cargo bed system includes a floor assembly for a cargo bed of a vehicle. The floor assembly is configured to transition back and forth between a standard floor position and an extended floor position. The floor assembly includes a plurality of floor sections each having a cargo support surface. The floor sections are folded when the floor assembly is in the standard floor position. The floor sections are unfolded when the floor assembly is in the extended floor position.

A vehicle cargo bed system includes a floor assembly that transitions back-and-forth between a standard floor position and an extended floor position. The floor assembly includes floor sections each having a cargo support surface. The floor sections are folded when the floor assembly is in the standard floor position. The floor sections are unfolded when the floor assembly is in the extended floor position. The assembly further includes first and second side wall assemblies of the cargo bed that transition back-and-forth between a standard wall position and an extended wall position. The first and second side wall assemblies each include an extendable portion and a fixed portion. The extendable portions extend and retract relative to the respective fixed portions when the first and second side wall assemblies transition back-and-forth between the standard wall position and the extended wall position.

A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.

A tailgate enclosure for use with a vehicle can include a plurality of cross-members, a first upright, a second upright, and only one additional upright. Each of the cross-members can be vertically spaced apart from an adjacent one of the cross-members and can include a first beam, a second beam, and a central beam having a first end and a second end, the central beam positioned at least partially between the first and second beams. The first upright can secure the first beam of each of the cross-members to a first sidewall of the vehicle and the second upright can secure the second beam of each of the cross-members to a second sidewall of the vehicle. The additional upright can be positioned along the central beam of each of the cross-members between the first and second ends of the central beam.
