Abstract: The present invention relates in general to a fifth wheel hitch and method of using a fifth wheel hitch that is mounted to a bed of a towing vehicle, and more specifically, to a fifth wheel hitch that is vertically secured to a kingpin of a fifth wheel trailer without requiring the use of adapters or extensions. One aspect of the fifth wheel hitch and method of use includes a hitch head assembly that is adjustable in height such that the fifth wheel hitch is compatible with different sizes of towing vehicles and fifth wheel trailers. The hitch head assembly also incorporates a funnel shaped design for receiving the kingpin of the fifth wheel trailer in a vertical fashion to prevent the kingpin from sliding horizontally out of the hitch head after being pulled forward by the towing vehicle. A four-way pivot joint accommodates instantaneous variations in pitch and/or roll attitudes between the towing vehicle and the fifth wheel trailer connected by the fifth wheel hitch.
