About This GMC Sierra 2500HD

This 2024 GMC Sierra 2500HD AT4X Crew Cab is a one-owner Texas truck that blends serious Duramax capability with premium AT4X refinement, showing just 9,000 miles since new. Delivered new to Shamaley Buick GMC in El Paso, Texas, it was well optioned from the factory and remains clean, stock, and highly desirable. Finished in Summit White over Obsidian Rush perforated leather, this Sierra is powered by the legendary 6.6-liter Duramax turbodiesel V8 paired with the Allison 10-speed automatic transmission, a dual-range transfer case, and an electronic locking rear differential, making it equally comfortable towing heavy loads or cruising long distances. Factory options include the gooseneck/fifth-wheel prep package with capped bed holes and 7-pin harness, dual alternators, and a high-idle switch, making this truck properly set up for work, towing, or RV duty. The AT4X trim adds a more aggressive stance along with upscale features such as heated and ventilated power front seats, heated outboard rear seats, dual-zone climate control, a power sunroof, Bose premium audio, running boards, sliding rear window, and a receiver hitch. Sitting on 18-inch wheels with Goodyear Wrangler tires, this Sierra delivers the perfect balance of heavy-duty strength, off-road confidence, and luxury comfort. With low miles, a clean history, and the right options, this AT4X is an excellent opportunity for anyone looking for a turnkey, top-tier HD diesel truck that's ready to work, tow, or travel in comfort.
