Forge perforated leather-appointed front seats provide both durability and comfort. The 15 head-up display projects essential driving information directly into your line of sight, while the premium Bose sound system with SiriusXM delivers entertainment throughout your journey.

Ultrasonic parking assist and automatic emergency braking provide additional confidence in tight situations. Wireless phone projection and charging eliminate cable clutter from your cabin.
The exterior presentation matches the truck's purpose and prestige.
