The exterior details also include color-matched trim and tinted windows, which keep the appearance consistent from panel to glass. The truck keeps the AT4's off-road-oriented look while preserving the clean lines of the crew cab body, and the added suspension and wheel package make the proportions easy to read from every angle. Roof marker lamps, a front license plate bracket, and the AT4 High Clearance Step are present as part of the exterior equipment, and the bodywork remains straightforward and purposeful. Inside, this Sierra 2500HD AT4 Crew Cab carries leather seats and a cabin built around the AT4 Premium Plus Package, the AT4 Preferred Package, and the Technology Package. A power sunroof brings additional light into the interior, while the head-up display places key information where it can be viewed without taking attention away from the road. The rear camera mirror is included as well, adding another way to monitor what is behind the truck. Adaptive cruise control and collision warning are part of the equipment list, and the cabin also includes a Wi-Fi hotspot and premium audio. All-weather floor liners are fitted to the truck, matching the rest of the interior's practical focus. Under the hood and beneath the body, this truck is equipped with the hardware expected of a heavy-duty diesel GMC, including the exhaust brake, engine block heater, 220 amp alternator, and federal emissions requirements. The 3.42 rear axle ratio is listed with the truck, and the GVWR is rated at 11,350 lbs. The Gooseneck / 5th Wheel Prep Package and hitch package are both included, giving the chassis the towing-related provisions noted on the window sticker. A winter grille cover is also part of the equipment, and the overall specification points to a truck prepared for cold-weather use and regular trailer duty. The AT4's suspension and underbody clearance work alongside the listed drivetrain and trailering hardware without needing any added explanation beyond the equipment itself. This 2025 GMC Sierra 2500HD AT4 Crew Cab presents the familiar heavy-duty GMC layout with the details that matter most in day-to-day use. The cab offers the expected space of a crew cab, while the combination of AT4 trim content, the selected option packages, and the visible exterior modifications gives the truck a specific but restrained appearance. The specification remains centered on capability, comfort, and the equipment already installed, from the black paint and tinted glass to the trailering and driver-assistance items on board. ## Dealership Information - Dealership: Lifted Trucks - Location: Lifted Trucks - Tucson, AZ, Tucson, AZ - Phone: (520) 329-4112 - [Location Details](https://www.liftedtrucks.com/locations/lifted-trucks-tucson-az): Address, phone, hours, and directions. ## Official Vehicle Listing https://www.liftedtrucks.com/for-sale/2025-gmc-sierra-2500hd-at4-crew-cab_4503599632000350 The official vehicle listing is the authoritative source for current pricing and availability. ## Disclaimer Our seasoned buyers meticulously select vehicles of the highest quality.
