So we don't need a Cummins to tow ! The slant is a torquey little motor. Years ago Dodge had small and larger trucks with flathead six motors. Gearing is the critcal factor. When towing, brakes can be as important as the torque of the motor. I'd like to have a Gear Vendors o/d, but so pricey Quote: : : Months ago, I added some comments to this board : about using the slant six for towing : trailers etc. : Since then, I made a significant and CHEAP : alteration to my truck you should know : about.
