Dealer notes
The 2026 GMC Sierra 1500 AT4 crew cab is new and in transit, arriving soon at Napleton Chevrolet Buick GMC in Beaver Dam. It carries the Duramax 3.0L turbo-diesel inline-six — the diesel option in the Sierra lineup — paired with a 10-speed automatic with Electronic Precision Shift, full-time 4WD, and a build that layers serious off-road hardware on top of a genuinely comfortable interior.
The exterior is Coastal Dune with a Jet Black with Kalahari Accents perforated leather interior.

The AT4 off-road and trailering stack here is comprehensive. The Preferred Equipment Group 4SB brings an off-road suspension, skid plates, a heavy-duty air filter, hill descent control, auto-locking rear differential, and red recovery hooks as the trail foundation.
The integrated trailer brake controller, Trailering Package, HD Surround Vision, Hitch View, Trailer Side Blind Zone Alert, trailer camera provisions, and the In-Vehicle Trailering System App handle everything on the tow side. The AT4 Premium Package adds off-road high-clearance steps — dealer installed — for easier access on the trail.
Wheels are 20-by-9-inch machined aluminum over 275/60R20 all-terrain blackwall tires, with a 255/80R17 all-season spare.
The Technology Package upgrades the cab with a multicolor 15-inch diagonal head-up display, a rear camera mirror with inside rearview auto-dimming, and a bed-view camera. The 13.4-inch diagonal premium GMC infotainment system includes Google built-in apps, wireless Apple CarPlay and Android Auto, and a Bose 7-speaker sound system.
A remote vehicle starter, keyless open and start, push-button start, wireless charging, a 120-volt interior power outlet, and a power sliding rear window with rear defogger round out the daily-driver features. On comfort, the driver and front passenger seats are both heated and ventilated through the perforated leather trim; second-row outboard seats are heated as well.
Rain-sensing wipers, front premium floor liners with removable carpet insert, a spray-on bedliner with GMC logo, rear wheelhouse liners, deep-tinted glass, and perimeter lighting finish the build. The engine block heater is included for Wisconsin winters.
LPO accessories on this unit include all-weather floor liners for the first and second rows, front and rear molded black splash guards, and a front license plate kit.
Napleton Chevrolet Buick GMC is on Kellom Rd. in Beaver Dam — about 35 minutes from Fond du Lac and convenient to Watertown, Hartford, and West Bend. Napleton has been family-owned for more than 80 years, and the process here is straightforward and low-pressure.
If the Duramax diesel in an AT4 build is what you have been looking for, this one is worth reserving before it arrives.
