Abstract: A sidewall assembly for a trailer including: a plurality of composite sandwich panels; and at least one composite side post coupled to the plurality of composite sandwich panels, each of the at least one composite side post including an outer post and an inner logistics post coupled to the outer post, wherein the outer post is formed with flexible metallic material and the inner logistics post is formed with hard metallic material.

Abstract: A multi-piece roof assembly for a trailer includes: a first section configured with a sandwich panel having a convex shape; and at least one additional section configured with a flexible sheet panel coupled to the first section and to at least one top rail assembly.

Abstract: Two-piece rail assemblies for truck trailers are provided. The two piece rail assemblies may include: a first rail configured with a first straight edge, and a second rail configured with a second straight edge coupled to the first straight edge of the first rail and configured with a curved edge to receive a cambered roof panel.

Abstract: A hook device for securing or releasing a deck panel used in a cargo section of a trailer, the hook device including: a guide bracket configured with at least first and second sides, the guide bracket including a groove formed on the first side and extending to the second side; and a hook configured to operate within the groove to secure or release the deck panel, the hook configured to secure the deck panel in a stored position when the hook is on the first side of the guide bracket and to release the deck panel in a work position when the hook is on the second side of the guide bracket.
