This truck handles both daily driving and weekend work with genuine versatility.

Inside, you'll find a workspace designed with your needs in mind. The heated and ventilated leather seats adjust multiple ways for your ideal driving position, while the premium infotainment system keeps you connected through Apple CarPlay and Android Auto. Dual-zone climate control ensures passenger comfort, and the heated steering wheel adds practical warmth during colder months. Multiple USB ports and power outlets—including a 120-volt bed outlet—keep your devices and tools powered throughout your day.

The truck's practical features extend to every detail. The spray-on bed liner protects your cargo area, LED cargo lighting illuminates loading and unloading, and the remote starter means you can warm up or cool down before you even reach the driver's door. The all-weather floor liners with AT4 logo help preserve the interior, while the machined aluminum wheels deliver both style and durability.

With 85,317 miles and proper maintenance behind it, this Sierra 1500 AT4 is ready for whatever comes next. The 5.3L V8 engine delivers dependable power with EPA ratings of 15 city and 21 highway, offering the torque you expect from a full-size truck. Whether you're towing a trailer, tackling off-road terrain, or managing daily tasks, this truck's combination of capability, comfort, and technology makes it a practical choice.
