A sidewall assembly for a trailer or van having a plurality of composite panels interconnected along the length of the trailer. The composite panels have a polyurethane core sandwiched between inner and outer metal panels in bonded relationship. The composite panels are affixed to a respective hat-shaped inner side post between adjacent vertical ends of the composite panels. A plurality of vertically arranged rivets affixes the composite panel to inner post and to an outer sidepost.

A body structure for a customized van is enhanced by providing a roof support element which is light in weight, strong, and easily shaped to conform to curved roof lines. The body structure comprises a rafter having upper and lower extruded rails and a plurality of gussets connected between the rails to join the rails in a single member. The rails are T-shaped in cross section with the upright of the T providing a point for connection of the gussets.

A construction for a cargo trailer side wall providing a plurality of horizontal scruff rails to extend farthest inwardly from the side wall and a plurality of post framing segments which do not extend inwardly past the scruff rails interconnecting one or more of the scruff rails and/or the floor and roof so as to provide a structural frame member reinforcing the side wall.

The invention provides a structural panel with an integrated bulkhead structure for promoting airflow within a refrigerated container, such as a refrigerated trailer. More specifically, the invention provides a front wall portion for a refrigerated container defining an aperture through which a refrigeration device may extend to the interior of the container. The front wall portion includes a bulkhead structure integrally formed with the front wall via a connecting structure defining one or more air ducts for promoting air flow from a floor of the container and up through an inlet of the refrigeration device. The invention also provides a front wall structure that minimizes hot spots in the container front wall by integrally-forming the front wall, connection structure, and bulkhead structure in a single structural component so as to minimize the use of fastener devices.

The invention provides a cargo bed structure comprising a sub-floor assembly comprising a plurality of cross members in spaced relation and a cargo bed defined by a longitudinally extending load-bearing deck overlying the sub-floor assembly and comprising a plurality of interlocking fiber reinforced polymer decking planks extending in a direction perpendicular to the cross members; an upwardly extending bulkhead assembly comprising at least one fiber reinforced polymer panel; a tailboard opposing the bulkhead and spaced apart therefrom; and two opposing upwardly-extending sidewalls, wherein each of the sidewalls and the tailboard comprise at least one fiber reinforced polymer panel pivotally mounted to the load-bearing deck.
