Expert Reply:
Air bags, 100% yes they're the best way to go. Since your 2021 GMC Denali 3500 has the B&W Gooseneck Hitch item # BWGNRK1020 you'll need to use a set of Firestones so you don't have to drill. I recommend the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs item # F2709.
The Firestone item # F2709 have a 7,500 lbs capacity that will level out the rear end of your Denali when you are towing your 5th wheel trailer. The custom fit mounting brackets and installation hardware are included.
I have linked an installation video below so you can see how to get them set up.
I also recommend adding the Firestone Air Command item # F2610 to your truck. This onboard compressor will allow you to adjust the PSI in your air bags from your phone.
