Your 2021 GMC Sierra 3500 AT4 with the 5th wheel prep package is able to fit the B&W Companion you were looking at without any issue, as the added height will not affect the fit of the hitch at all. The only factor is going to be if you have a long bed or a short bed, which will determine if you need a sliding hitch or a fixed hitch.

The correct fit for your 2021 GMC Sierra 3500 AT4 with the 5th wheel prep package is one of the following:

- 8 Foot Long Bed: B&W Companion OEM 5th Wheel Hitch for Chevy/GMC Towing Prep Package # BWRVK3710

- 6-3/4 Foot Short Bed: B&W Companion OEM 5th Wheel Hitch with Slider for Chevy/GMC Towing Prep Package # BWRVK3775

The Companion is an awesome choice for a 5th wheel hitch as it is widely considered to be the best in the industry due to its behemoth jaw system that grips the king pin like a vice to ensure there is little to no movement. That results in a much quieter, more comfortable towing experience than any other hitch can provide.

I have added links below to a couple video reviews for you to check out as well of the Companion if you'd like to take a look.
