SLE
The SLE builds on Pro with tech-forward upgrades that make every task simpler. You’ll notice the cockpit first: a crisp 13.4-inch diagonal center touchscreen and a 12.3-inch diagonal digital Driver Information Center keep towing data, trail maps, and audio right where you want them. The Traction Select System with Tow/Haul mode helps you dial in throttle response and shift mapping to your load and terrain, while its 17-inch machined aluminum wheels add a confident stance.

The available MultiPro™ Tailgate and MultiPro Tailgate Audio System by Kicker® turn the bed into a staging area for tools, tailgates, or on-site walk-throughs.

Massive 35-inch Goodyear® Territory MT tires bolster traction on mud, rock, or loose soil, while precise on-road manners remain intact when you head back to the highway.
