A gooseneck hitch is designed for use in a pickup truck and is similar to a Fifth Wheel hitch. The difference between the two is that the gooseneck uses a ball and coupler versus a kingpin and fifth wheel hitch. Typically, the trailers that are most commonly used with a goosenecks hitches are horse and livestock trailers.
Gooseneck hitches are offered in a few types of configurations. They are designed to be mounted above or below the pickup bed. Either design (above or below) allows for minimal obstruction when the ball is not in the towing position. This permits full use of the pick-up bed.
