2023 Yukon XL AT4 Sterling Metallic Walk Around

Here’s a tour of a new GMC Yukon Denali XL AT4 inside and out. The color is Sterling Metallic with the Jet Black Brandy Accent interior.
I show the standard features of the AT4, and highlight what’s in the added Technology Package, Premium Capability Package, and the Max Trailering Package. You can also see the panoramic sunroof and power assist steps in action.
