Trailering is this truck's forte. Heavy-duty trailering equipment, fifth wheel provisions, and gooseneck trailer wiring harness make towing straightforward and safe. The tow/haul mode in the transmission optimizes shifts for loaded conditions, while the auxiliary cargo lamp illuminates your trailer during backing operations.
