This is kind of a grey area. We were tested as a fifth wheel hitch and are approved as a fifth wheel hitch. According to DOT regulations because it is a fifth wheel hitch we does not need safety chains. However we do utilize a gooseneck ball to secure the fifth wheel hitch into place creating a solid base with no moving points. On conventional gooseneck trailers chains are required due to the latching mechanism on the gooseneck trailer. The Andersen Ultimate Connection does not utilize a latch nor does it pivot at the point of the ball. Our unconventional setup is much like the OEM puck system that is utilized to accept fifth wheel hitches sold in the newer trucks today. here
