I have used B&W role over and fifth wheel hitches for the last 10 years and have nothing but respect for the quality they put into their equipment.

Man let me tell you, these guys know their stuff. It's a great product and I love the B&W. Fits in my 2018 High County like socks on a rooster. The only down side to it is that it's extremely heavy. The base is about 250lbs and it is not a one person job.

Product works well. Would have give. It five stars but the weight and lack of a defined means to lift it are my concerns. Lifting handles would be a great addition. I have added a small winch on the ceiling of my shop to lift in and out of my truck.

Which B&W Companion Hitches Fit a 2019 Chevy Silverado 3500 with Factory Prep Package
Are you certain that it is a Patriot hitch and not a Companion? I ask because there isn't a Patriot version that fits the factory puck system in any of the trucks that have that option (Ford, GM, Ram, or Nissan). If the hitch is # BWRVK3700 then it is a Companion model. If your 2019 Chevy Silverado 3500 is a long bed then yes, Companion hitch # BWRVK3700 does indeed fit the factory prep package in your new truck. If your truck is a short bed you would either need Companion slider hitch...

Replacement B&W Companion Slider Base for 2020 Chevy Silverado 2500 with Factory Pucks

This will hook right up to your existing Companion head so that it can mount to the pucks in your truck bed. The whole hitch including both the head and slider base is part # BWRVK3775 GM changed the puck configurations for the 2020 model Silverados so the Replacement Slider Base # BWRVB3770 that you referenced, which was designed for 2016-2019 Chevy/GMC trucks, will...

Would Hitch Head from B and W Patriot fit B and W Companion Hitch Base
The Companion and Patriot hitches from B and W are similar but they are different enough that they are not interchangeable. So you'd have to go with a new hitch that fits your 2021 Chevy Silverado 3500 with the OEM rail kit part # BWRVK3775.

B&W does have Companion 5th wheel hitches that are compatible with the OEM puck system that comes from the factory on your 2016 GMC Sierra 3500. For a short bed we recommend using the slider version # BWRVK3770 for cab clearance when making tight turns.
