Hello Howard. We do offer a B&W Companion hitch for the puck system in a 2021 GMC 2500. The RVB3700 you mentioned will only fit the GMC puck system on a 2015-2019 model. After 2019 GMC changed their puck system footprint so the RVB3700 will not fit a 2021. For the puck system in your 2021 GMC 2500 you will need the following:
- B&W Companion OEM 5th Wheel Hitch for Chevy/GMC Towing Prep Package - Dual Jaw - 20,000 lbs # BWRVK3710
