Description for 2025 GMC Sierra 1500 AT4 Truck

The 2025 GMC Sierra 1500 AT4 is a full-size pickup engineered for premium off-road performance with high-end comfort and technology. This AT4 model is equipped with a 3.0L I6 Duramax Turbo-Diesel engine paired with a 10-speed automatic transmission, delivering strong torque, efficiency, and confident towing capability. Four-wheel drive and a host of trail-focused enhancements make the AT4 especially suited for navigating rough terrain while maintaining everyday drivability.

Finished in Summit White with Jet Black leather interior accented by Kalahari stitching, the Sierra AT4 blends rugged appeal with refined styling. Off-road components such as a factory 2-inch suspension lift, Hill Descent Control, and skid plates work in concert with the Auto-Locking Rear Differential, heavy-duty air filter, and AT4-specific high-clearance step rails to enhance capability in challenging environments. Red vertical recovery hooks and black chrome grille insert bars further distinguish the AT4s exterior.

The interior is equipped for both utility and comfort. Heated and ventilated front seats and heated outboard rear seats ensure climate comfort year-round. The AT4 Premium and Preferred Packages include luxury touches such as a power-adjustable steering column, leather-appointed seating, and a premium Bose 7-speaker audio system. Storage and power access are thoughtfully integrated throughout, with multiple USB ports (including Type-C), 120-volt outlets in the cabin and bed, and a wireless charging pad.

For towing, the Sierra AT4 includes the Trailering Package with Trailer Camera Provisions, Hitch Guidance, Hitch View, and an Integrated Trailer Brake Controller. The In-Vehicle Trailering App and Trailer Side Blind Zone Alert enhance visibility and safety when towing, while Ultrasonic Front and Rear Park Assist and Rear Cross Traffic Braking assist in tight spaces.

Technology is front and center with HD Surround Vision, a large Navigation System interface, OnStar Services capability, SiriusXM with 360L, and Wi-Fi hotspot functionality. Rear Pedestrian Detection and other driver-assistive safety features contribute to enhanced awareness around the vehicle.

The cabin is further refined with thoughtful details such as rain-sensing wipers, a floor-mounted center console with removable carpet inserts, power sliding rear window with rear defogger, and universal home remote integration. Deep-tinted glass and perimeter lighting round out the functional exterior enhancements.

Additionally, all purchases are backed by the Walt Massey 3 Day Money Back Guarantee. Under this policy, you may exchange your vehicle within three business days of purchase, provided it is returned in "like new" condition with fewer than 300 miles driven. If the vehicle has over 300 miles, a \$1.00 per mile fee applies for the additional distance.

The 2025 GMC Sierra 1500 AT4 is well-suited for buyers who prioritize off-road readiness, premium features, and advanced towing support in a full-size truck platform.
