The Sierra 1500 AT4 is purpose-built for off-road performance and refined capability-it's the adventure lover's choice.

Power comes from a **3.0L Duramax Turbo-Diesel engine** with a 10-speed automatic, delivering impressive torque and efficiency for tackling rough terrain. The AT4 rides on aggressive **18" LT275/65R18C Goodyear Wrangler Territory mud-terrain tires** and features **off-road-tuned suspension** engineered for rocks, ruts, and rugged trails. An **integrated trailer brake controller** and Tailgate with **EZ Lift assist**, power lock, and release add practical off-road utility.

Inside, luxury and adventure merge: a **Bose Premium Sound System**, heated rear outboard seats, and available **Head-Up Display** keep you comfortable and informed. **Rainsense automatic wipers** adapt to changing weather. The AT4 proves that serious off-road capability doesn't mean sacrificing refined comfort. Ready to explore? Call Markquart Motors at (715) 833-0444 to schedule an AT4 test drive.
