Dealer notes
A new 2026 GMC Sierra 1500 AT4 4WD crew cab with a Duramax 3.0L turbo-diesel inline-six, here at Napleton Chevrolet Buick GMC in Beaver Dam. Sterling Metallic — a cool, medium metallic silver — rides over a Jet Black interior with Kalahari Accents finished in perforated leather front seat trim.
This AT4 is built from the ground up for buyers who split their time between the trail and the hitch: off-road suspension, skid plates, hill descent control, an integrated trailer brake controller, and dealer-installed high-clearance off-road steps, with heated and ventilated seating and a layered camera system to bring comfort and visibility along for the ride.

The AT4 Equipment Group builds a serious off-road and trailering foundation. Skid plates and an off-road suspension protect the drivetrain and smooth out rough ground, while hill descent control and an auto-locking rear differential keep things pointed in the right direction when traction gets thin.
Red recovery hooks are mounted and ready. Dealer-installed high-clearance off-road steps from the AT4 Premium Package make cabin entry easier without sacrificing clearance. On the trailering side, the integrated trailer brake controller, a full Trailering Package, in-vehicle trailering system app, trailer side blind zone alert, hitch view, and trailer camera provisions mean this truck is wired for the job before you even back up to the hitch.
The Technology Package adds a rear camera mirror, a 15-inch multicolor head-up display, and a bed view camera — three distinct views that together give you a clearer picture of what's behind and alongside the truck than a single mirror ever could. HD Surround Vision, ultrasonic front and rear park assist, and rear cross traffic braking round out the camera and sensing suite.
Inside, the AT4 Preferred Package brings a rear sliding power window and universal home remote. The cabin runs a 13.4-inch GMC Infotainment System with Google built-in apps, wireless Apple CarPlay and Android Auto, a premium Bose 7-speaker sound system, wireless charging, a 120-volt interior power outlet, and a remote vehicle starter.
Comfort is covered by heated and ventilated front seats, heated second-row outboard seats, front rain-sensing wipers, and a power sunroof. The 20 x 9 machined aluminum wheels wear 275/60R20 all-terrain tires, and a 220-amp alternator keeps up with the electrical load.
Napleton Chevrolet Buick GMC is at N8167 Kellom Rd. in Beaver Dam — about 45 minutes from Madison, an hour from Milwaukee, and 35 minutes from Fond du Lac, and a straight shot for shoppers coming from Portage, Waupun, Horicon, Juneau, and Fox Lake. The store has been family-owned for over 80 years and runs a no-pressure process.
When you're ready to put this diesel AT4 through its paces, we'll have it fueled up and waiting.
