I was wondering what others use to minimize slipping when driving in cold, icy conditions. I drive a 94 Dodge Cummins 2500 4x2 with new A/T tires, limited slip and 600 lbs in the back. I still have had to work real hard at not sliding into the garage door frame when slowly entering. Is this truck just too heavy in the front and too light in the back with mega torque?
