A flatbed trailer design that unitizes the three main components of a trailer bed, the main rails, the cross members and the floor, to create a lightweight and stronger trailer. The trailer design comprises two main rails having dual webs and a plurality of shouldered cross members. These dual web main rails and shouldered cross members have top flanges that are formed by the upper plane of the flooring members. In addition, intermediate flooring supports are used between cross members. A flooring/cross member design for box-type (e.g., van) trailers, box-type bodies or even container bodies, whose top flanges of the cross members are formed by the upper plane of the flooring and whose flooring supports are intermediate, exhibiting a combined lower height. This result provides more interior space for these type of trailers while maintaining, or even reducing, the size of the cross member. This unitized flooring also forms the lower flange of the box or chassis, thereby increasing the strength of the box itself.
