I think these trucks need a Sub-Zero Weather Package for all trims levels which would include the already available Engine Block Heater, Supplemental Heater Element and Heated Mirrors. Incorporate a power radiator/grill vent panel to open or block air passing over the radiator for faster warm ups then automatically opens once desired running temps are reached. We know diesels take longer to heat up and letting them idle or warm up is not green. Also include Heated Seats and Steering Wheel with non-fog/frost coating/film on rear and side glass.
