The SLT steps into serious capability with a robust 5.3L V8 engine and 10-speed automatic transmission-a major jump from lower trims. Built for trailering and hauling, it includes an available Max Trailering Package, automatic locking rear differential, heavier-duty springs, and increased rear axle ratings. Standard safety tech like Trailer Side Blind Zone Alert keeps you confident when towing. The SLT rides on premium 18" machined aluminum wheels with Dark Grey Metallic accents, includes black vertical recovery hooks, and can add skid plates for rugged durability. If towing and hauling are central to your needs, the SLT delivers V8 performance and dedicated towing tech. Contact Markquart Motors at (715) 833-0444 to discuss SLT options and current availability.
