Question:

Just purchased a Demco Autoslide 18k fifth wheel hitch from you. I need to attach a Rockwood 2007 Signiture Ultra Lite fifth wheel. Do I need any kind of adapter plate for the pin box to make this work? Thanks.

The Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider part # DM8550034 works with most standard pin boxes for the exception of Sidewinder or Revolution's. However, if you have one of the following pin boxes: Glide Ride, Mor Ryde, Trailair Tri Glide, Trailair Flexair, Rota Flex, and 5th Airborne then you will need a locking plate to prevent the kingpin from rotating inside your hitch. I have attached the correct locking plates for the above pin boxes for you below.

MOR/ryde Pin Box: part # DM6025

Trailair Tri-Glide Pin Box: part # DM6095

Original 5th Airborne Pin Box: part # DM6026

Glide Ride Pin Box: part # DM6036

Trailair Rota-Flex/Trailair Flexair Pin Box: part # DM6171

Extended 5th Airborne Pin Box: part # DM6062

Hey Jerry, GM moved the placement of their puck systems starting with 2020 models so you are correct that the pucks would have the hitch not sit directly over the axle. GM did the math and made sure that this placement wouldn't adversely affect…
