These trucks come equipped with two-speed transfer cases, skid plates, and trail hardware on Z71, AT4, and AT4X variants. Advanced camera technology provides up to 14 views including underbody monitoring, while ProGrade and trailering systems with towing-focused assists make every job safer and easier.
