ABSTRACT:
A floating pin fifth wheel hitch is disclosed. This hitch uses separate points to bear the vertical and horizontal forces created by the towed vehicle. By allowing the pivot point to float and thus bear only the horizontal forces of the trailer it can be placed rearward of the rear axle of the towing vehicle without adverse affects to the handling characteristics of the truck and trailer combination. The hitch is further supplied with a vertical force or weight bearing slide that can be placed above or in front of the rear axle of the towing vehicle. By splitting the forces created by the trailer and letting them be born by the towing truck a hitch is created that allows for a short turning radius while still shortening the overall length of the truck and trailer combination and keeping the weight of the trailer in a position that does not effect the handling or ride characteristics of the truck.
