Dealer notes
This 2026 GMC Sierra 2500HD AT4 — a new four-door crew cab in Summit White with a Jet Black with Kalahari Accents interior — is in transit, arriving soon at Napleton Chevrolet Buick GMC in Beaver Dam. While plenty of heavy-duty trucks can tow, this particular AT4 build combines gooseneck/fifth-wheel prep, a 220-amp alternator, Snow Plow Prep/Camper Package, and the full X31 Off-Road Package on the gas-powered 6.6L V8, making it the ready-for-anything workhorse that doesn't require a diesel to get the job done.
The Summit White exterior is paired with perforated front leather seat trim in Jet Black with Kalahari Accents.

Built to work. The Snow Plow Prep/Camper Package adds a 220-amp alternator, increased front GAWR, skid plates, and roof emergency light provisions — a foundation that goes well beyond a standard AT4.
Gooseneck/fifth-wheel prep means the bed is pre-configured to accept a gooseneck or fifth-wheel hitch when you're ready to put it to work. The ProGrade Trailering System integrates a bed-view camera, trailer camera provisions, Trailer Side Blind Zone Alert, and Rear Cross Traffic Alert into a connected trailering suite, while HD Surround Vision gives you a bird's-eye perspective around the truck.
A spray-on bedliner with GMC logo, 120-volt bed-mounted power outlet, and LED cargo area lighting round out the working end of the truck.
Off-road and on the road. The AT4 Premium Plus Package brings power-retractable black assist steps, a power sunroof, and the Technology Package. Underfoot, the X31 Off-Road Package teams with 20-inch high-gloss black aluminum wheels and LT275/65R20 all-terrain blackwall tires.
The AT4 Equipment Group layers in a Gloss Black header grille and grille insert bars, front rain-sensing wipers, a remote vehicle starter, keyless open and start, and Smoked Amber LED roof marker lamps. The AT4 Preferred Package adds a power sliding rear window with defogger and Universal Home Remote.
Inside, thoroughly equipped. Ventilated and heated front seats, heated second-row outboard seats, and perforated leather seat trim create a comfortable environment for every occupant.
The 13.4-inch diagonal premium GMC infotainment system includes Google built-in apps for navigation and voice assistance, wireless Apple CarPlay and Android Auto, and a mobile hotspot. A Bose premium audio system, wireless charging, a multicolor 15-inch diagonal head-up display, and a rear camera mirror handle entertainment and awareness.
Front and rear premium floor liners with removable carpet inserts, rear wheelhouse liners, and black LPO molded splash guards keep things clean when the work follows you inside. The Safety Alert Seat, Ultrasonic Front and Rear Park Assist, forward collision mitigation, and pedestrian impact prevention cover driver assistance.
USB ports front and rear, 120-volt instrument panel outlet, and SiriusXM with 360L trial subscription fill out connectivity.
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 coming from Hartford, West Bend, and Portage. Napleton has been family-owned for over 80 years, and the process here is low-pressure from first look to final paperwork.
When this AT4 arrives, bring the trailer hitch and see what the 220-amp alternator and gooseneck prep can do for your setup.
