I was extremely disappointed when I bought my '06 Laramie and found the knob on the dash for the transfer case. Some of the other models still have the lever shifter for four wheel drive. Has anyone done a conversion to the lever shifter? I drive on snow and ice most of the winter, and want to be able to shift into four wheel drive when I need to. Fumbling with a little knob on the dashboard just doesn't work when you need to shift. JH
