At least one limited articulating female hitch mechanism and trailer for mounting to a conventional trailer hitch male connection member mounted on a towing vehicle. The hitch mechanisms are pivotal in only the vertical plane. The combination comprises a trailer having a horizontally disposed load supporting frame mounting of swivel (or 360 degree horizontally rotating) wheel assemblies about 360 degrees. This arrangement, coupled with the hitch mechanism, assures the trailer tracks the towing vehicle so that the sides of the towing vehicle and the sides of the trailer remain constantly parallel to each other Reduced trailer size and weight, reduced storage requirements, ease of backup maneuvering and avoidance of road hazards, vehicles, pedestrians and objects is thus facilitated by such arrangement. This system also reduces the weight that is placed upon the towing vehicles rear axle by the trailer hitch mechanism and therefore ensures that the full weight of the front steering wheels of the towing vehicle remain on the road surface so that the towing vehicle steering is not diminished by an uplifting force.
