mmmmm A 4,000 pound JK thinks it's pulling what 40,000 pound semi? and on an icy surface at that?
Kind of reminds me of the Budweiser commercial with the young Kleidsdale thinking it's pulling the wagon. Everytime the semi stopped adding the gas, the JK started sliding on the strap.
Not saying that a CJ, YJ, or TJ would do any better mind you.
