Summer has a way of revealing what a truck is really made for. One weekend might call for towing a boat to the lake, while the next involves hauling camping gear or navigating a trail that quickly leaves the pavement behind. GMC approaches that challenge with two distinct pickups: the full-size Sierra 1500 and the midsize Canyon. Each delivers impressive capability, but they serve different kinds of adventures. If you're comparing trucks in Tupelo, MS, exploring our inventory of new GMC trucks is a great place to see which model best fits your lifestyle. 2026 GMC Sierra 1500: Built for Heavy Lifting The Sierra 1500 remains GMC's flagship pickup because it combines substantial towing capability with the technology to make that capability easier to use. The standard TurboMax ™ engine produces 310 hp and a class-leading standard 430 lbs. ft. of torque, giving every Sierra 1500 a strong foundation for towing and hauling. Drivers needing maximum capability can choose the available Duramax® 3.0L Turbo-Diesel, which allows properly equipped models to tow up to 13,300 lbs.

The available ProGrade Trailering System simplifies trailer setup and monitoring, while up to 14 available camera views provide excellent visibility when backing into campsites or launching a boat. Available Super Cruise® adds hands-free driver assistance on compatible roads, even while towing with a properly equipped trailer.
