To add a gooseneck hitch to your 2021 GMC Sierra 1500 Denali, I recommend the B&W Turnoverball Underbed Gooseneck Hitch item # BWGNRK1019. It fits all three bed lengths and the diesel models. This system includes custom fit brackets that bolt into existing holes in your Sierra's frame. The only drilling you will need to do is in the bed when you add the holes for the receiver and the safety chains.

Please note that if you have the CarbonPro box you can not install a gooseneck hitch. None of them are compatible.

I have linked an installation video below so you can see how to get this gooseneck hitch set up.

To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C53CR. This harness puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel trailer easier and more convenient.
