The **2025 GMC Sierra 1500 AT4** is purpose-built for off-road performance and adventure. It's powered by a **3.0L Duramax Turbo-Diesel engine** with a **10-speed automatic transmission**, delivering impressive torque and efficiency for trail work and hauling.

Off-road credentials include **aggressive 18" Goodyear Wrangler Territory mud-terrain tires**, **off-road-tuned suspension**, and an **integrated trailer brake controller**. The **Tailgate with EZ Lift assist**, power lock, and release adds real utility for remote camping and exploration.

Inside, the AT4 doesn't skimp on comfort: **Bose Premium Sound System**, **heated rear outboard seats**, and an available **Head-Up Display** keep you pampered between adventures. **Rainsense automatic wipers** handle changing weather seamlessly.

The AT4 balances rugged capability with refined luxury-ideal if you want a truck that's equally at home on a backcountry trail or a city street. Call Markquart Motors at **(715) 833-0444** to schedule a test drive or learn more about AT4 availability and pricing.
