Built to Tow Heavy
Which Engine for
Choose the gas 6.6L V8 if you plow, haul, and tow moderate loads — capable, lower up-front cost, and great for winter work. Choose the Duramax diesel if you tow heavy and often (gooseneck trailers, equipment) and want maximum capability and that 975 lb-ft of torque for the long haul. We keep both on the lot — drive them back to back.
