This GMC is a premium heavy-duty truck that combines exceptional capability, rugged styling, and upscale comfort. Designed for drivers who need serious towing and hauling power without sacrificing refinement, the AT4 trim adds a bold and adventurous look while delivering the strength and durability GMC trucks are known for. With aluminum wheels, fog lights, side steps, turn signal mirrors, and distinctive styling, it makes a powerful statement wherever it goes. Inside, the spacious and well-appointed cabin is built for comfort with leather seats, heated seats, a heated steering wheel, memory seating, heated front seats, power windows, and an auto-dimming rearview mirror. Whether you're towing equipment, heading to the job site, or embarking on a long-distance trip, it provides a comfortable and premium driving experience. Technology highlights include remote start, Bluetooth integration, satellite radio, smart device integration, WiFi hotspot capability, rain-sensing windshield wipers, steering wheel audio controls, keyless entry, and a backup camera, helping keep every drive connected and convenient. This vehicle has no reported accidents and only one previous owner, making it an excellent option for anyone looking for a well-maintained and dependable heavy-duty truck. Safety features include blind spot monitoring, lane departure warning, cross-traffic alert, stability control, traction control, anti-lock brakes, tire pressure monitoring, and a spare tire to help provide confidence behind the wheel. The limited slip differential and engine block heater further enhance capability and year-round usability. With its combination of heavy-duty performance, premium comfort, and advanced technology, this is a truck you will definitely want to come see in person.
