ABSTRACT:
A trailer hitch attachment mounting between a towing vehicle and a trailer for simulating a "5th" wheel trailer hookup. The hitch mounts to the towing vehicle undercarriage rearwardly adjacent the rear axle and includes a drawbar that extends to the towing tongue of the trailer. The drawbar is pivoted at a front end about a primary axis directly behind the rear axle and at a rearward end, about a secondary axis at the connection to the trailer towing tongue. A lockout mechanism is provided for alternately locking the drawbar against pivotal motion about one or the other the pivot axes, so only pivotal motion will be allowed about only one axis at any given time. The pivot axes are alternated according to relative angular movement of the towing vehicle relative to the trailer.
