Dealer notes
The 2026 GMC Sierra 1500 AT4 crew cab is a new truck on the lot at Napleton Chevrolet Buick GMC in Beaver Dam, WI — and this particular build pairs the AT4 Premium Package, Technology Package, and Preferred Equipment Group 4SB with a 6.2L ECOTEC3 V8 that separates it from every AT4 powered by a smaller engine. It arrives in Onyx Black over a Jet Black with Kalahari Accents interior trimmed in perforated leather, with a 10-speed automatic transmission and 4WD.

The off-road hardware on this truck is the full AT4 stack. Off-road suspension and skid plates handle the rough ground; 20 x 9 machined aluminum wheels wrapped in 275/60R20 all-terrain tires put traction where the trail demands it.
Red recovery hooks are up front, an auto-locking rear differential engages when things get slippery, and hill descent control manages steep grades. The AT4 Premium Package adds the Off-Road High Clearance Step — a sticker-printed package name we keep verbatim — making entry and exit easier without sacrificing approach angle.
If you run a trailer, the Preferred Equipment Group 4SB includes an integrated trailer brake controller, the In-Vehicle Trailering System app, trailer side blind zone alert, hitch view, trailer camera provisions, and HD Surround Vision camera system, so hitching up and pulling are fully supported from inside the cab.
The interior is equally deliberate. Heated and ventilated front seats plus heated second-row outboard seats handle Wisconsin's full range of seasons. Wireless charging, a 120-volt interior power outlet, and USB ports in the center console keep devices powered.
The Technology Package brings a rear camera mirror, a multicolor 15-inch diagonal head-up display, and a bed view camera. The AT4 Preferred Package adds a power sliding rear window with rear defogger and a universal home remote.
Audio comes from a Premium Bose 7-speaker sound system. The 13.4-inch diagonal premium GMC infotainment system runs Google Built-In apps including navigation and voice assistance, pairs wirelessly with Apple CarPlay and Android Auto, and connects via a SiriusXM with 360L trial subscription and available mobile hotspot.
A remote vehicle starter system, keyless open and start, push-button start, rain-sensing front wipers, front and rear park assist, rear cross traffic braking, rear pedestrian detection, and GMC Pro Safety round out the safety and convenience picture. Inside the box, a spray-on bedliner with the GMC logo and LED cargo area lighting make it a working truck bed, not just a pretty one.
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 straightforward drive for shoppers from Watertown, Columbus, Mayville, and Randolph. Napleton has been family-owned for over 80 years, and we don't do pressure.
If the 6.2L AT4 is the truck you've been spec-ing out, we'd be glad to walk through it with you.
