Dealer notes
This 2026 GMC Sierra 2500HD AT4 is a new four-door crew cab with 4WD, powered by a 6.6L V8, and it is currently in transit, arriving soon at Napleton Chevrolet Buick GMC in Beaver Dam. It wears Summit White over a Jet Black with Kalahari Accents interior — a pairing that sets it apart from the darker and diesel-powered AT4 builds also on their way to this store.
Where those siblings lead with turbodiesel complexity, this one makes its case with the natural pull of a big-displacement gas V8 and the AT4's proven off-road and heavy-duty bones.

The AT4 trim brings GMC's off-road hardware and a distinctly blacked-out appearance package to the 2500HD platform. The four-door body gives rear-seat passengers the space that long workdays — or long drives up to Fond du Lac — demand, and the 4WD system means it is ready whether you point it toward a job site off the pavement or into a Wisconsin winter.
The 6.6L V8 is the straightforward, high-displacement gas choice in a lineup where diesels often dominate the conversation: no diesel exhaust fluid, no particulate filter, just displacement doing the work.
Because this unit is in transit with a thin equipment record, we are not listing individual options here — full window sticker details will be confirmed when the truck arrives. What is fixed: the year, trim, drivetrain, engine, body style, and colours listed above are drawn directly from the vehicle record.
Reach out to the store and we will share every confirmed sticker line as soon as it is available.
Napleton Chevrolet Buick GMC sits at N8167 Kellom Rd. in Beaver Dam — about 45 minutes from Madison, an hour from Milwaukee, and 35 minutes from Fond du Lac, making it a straightforward drive from Watertown, Columbus, and Hartford as well. Napleton has been family-owned for more than 80 years, and the process here is low-pressure: we show you what we have, answer your questions, and let the truck speak for itself.
If you want to be notified the moment this one lands, let us know and we will keep you updated.
