Modular truck cargo area body

摘要

A modular frame structure for a cargo area of a truck includes rails, side structures and pre-fabricated assemblies. Each of the rails include elongated portions having interlocking seats for interdigitally engaging the rail portions. The interlocked rail portions also urge against and counterpose each other for reducing the stress on the interlocking seats. The rails are fastened or welded to the side structures and the pre-fabricated assemblies to complete the modular structure.
