Dealer notes
This new 2026 GMC Sierra 3500HD SLE regular cab, long bed, 4WD is on the lot at Napleton Chevrolet Buick GMC in Beaver Dam, WI — and it arrived stacked with every package a serious working-truck buyer would configure from scratch: the X31 Off-Road Package, Snow Plow Prep/Camper Package, Gooseneck/5th Wheel Prep Package, and Sierra HD Pro Safety Plus Package, all on one window sticker. The exterior is Sterling Metallic, a warm light silver, over a Jet Black cloth seat interior.

The powertrain and chassis packages tell the story. The Duramax 6.6L Turbo-Diesel V8 is paired with an exhaust brake and a 220-amp alternator — both sticker-confirmed — so it is ready for long grades and high electrical demands.
The Snow Plow Prep/Camper Package and the Gooseneck/5th Wheel Prep Package mean the truck left the factory provisioned for a front plow, a gooseneck ball, or a fifth-wheel king pin; no dealer add-ons required. The X31 Off-Road Package adds an off-road suspension tune, skid plates, and hill descent control for the days the job site is not on pavement.
GVWR is 11,800 lbs. with single rear wheels, and the 3.42 rear axle ratio comes from the sticker. LT275/70R18E all-terrain tires — including a matching spare — ride on 18-inch machined aluminum wheels.
The SLE Convenience Package and Preferred Equipment Group 3SA build a capable cab around that drivetrain. The driver seat is a 10-way power adjuster with lumbar; dual-zone automatic climate control handles Wisconsin winters; heated and auto-dimming power-adjustable vertical trailering mirrors are already on the truck.
Keyless open, push-button start, and remote start (via the Remote Start Package) round out daily-use convenience. The 13.4-inch diagonal premium GMC Infotainment System supports wireless phone projection and a mobile hotspot, with two USB charge/data ports and steering-wheel audio controls.
There are also 120-volt outlets at both the instrument panel and in the bed.
The Sierra HD Pro Safety Plus Package adds front and rear ultrasonic park assist, rear cross-traffic alert, and trailer side blind zone alert to the forward collision mitigation, pedestrian impact prevention, rear camera, and brake assist that are already part of Sierra HD Pro Safety. The spray-on bedliner and black tubular assist steps are dealer-installed accessories already on the truck, and a winter grille cover and front license plate kit round out the sticker.
The engine block heater is also included — a practical detail when January hits Dodge County.
Napleton Chevrolet Buick GMC is at N8167 Kellom Rd. in Beaver Dam, about 45 minutes from Madison and convenient for shoppers coming from Portage, Waupun, Juneau, and Horicon. Napleton has been a family-owned automotive group for more than 80 years and operates with a no-pressure process.
If you need a truck that works as hard as you do, this Sierra 3500HD is worth a look before the snow flies.
