    We pull our 2020 320MKS with a 2003 Chevy 2500HD SB Duramax Silverado SWD. We added Sumo springs, Cold air intake, Hawk performance brake pads and a Sidewinder hitch. Pushing the truck GVWR but pulls and stops fine.

    Good Morning,
    We tow our 2021 320 MKS with a 2011 Ford F250 with the 6.7 power stroke. We have towed over the summit in Wyoming at 55 MPH with no heat issues. I am planning on adding airbags to the rear suspension as there is a slight sag with the 5th wheel on but not much. We can head north on I25 and pull at whatever speed I choose with no issues.
