Trailer having improved side wall

A wide variety of trailers are known for carrying cargo. For example, van type trailers typically include a deck assembly supported by a side wall structure, wheels and front legs. The deck assembly may include Longitudinal floor boards and transverse cross-members, such as I-beams, extending between opposing bottom rails. The deck transfers its load to the bottom rails, wheels, and, depending upon whether or not the trailer is coupled to a tractor or is free-standing, to a tractor fifth wheel or to retractable front legs on the trailer. A cargo trailer includes a floor and a side wall extending vertically upward from a side edge of the floor. The side wall includes a plurality of generally vertical posts. Each post defines an interior surface disposed in a generally common plane and a recessed portion. A scuff band is received within the recessed portions so that at least a portion of the scuff band is outward of the common plane.
