Industry Standard Rail Adapter for a 2021 GMC Sierra 2500 w/ the OEM Puck System

Question:

Two year camper owner still learning. Just upgraded for a 2021 GMC 2500HD with factory 5th wheel prep package. Currently have a Anderson rail mount. Need info on Puck to rail mount system. Anderson was NO help. Really dont want to buy a new hitch. How do I make the rail mount hitch work with the pucks in my GMC bed?

To mount your Anderson 5th wheel hitch to your 2021 GMC Sierra 2500's factory rail kit you will need the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 21K item # DM6333. This adapter will provide you with a set of industry standard rails.
