A trailer coupler has a fixed frame portion that is connected to a moving frame portion with link arms. The link arms are attached to torsion components that are affixed to both the fixed frame portion and moving frame portion with the moving frame portion located between ends of the fixed frame portion. The moving frame portion has a resting position where the torsion components are at rest and a displaced position where external forces have caused the torsion components to move. The moving frame portion can be displaced through rotation or vertical movement by external forces.

An upper deck frame assembly for a trailer chassis includes a flushed floor section defining a first floor height, and a header section, with a header, forward of the flushed floor section and defining a second floor height above the first floor height. A towing assembly may be secured to the header. A reduced size header section increases usable floor space, and the towing assembly is securable to the header.
