It's not often you get a chance to see a diesel Wrangler submerged. This is even truer on U.S. soil. This section of the Mounds off-road park in Mt. Morris, Michigan, looked like a flooded bombing range. Jeep engineering provided the diesel JK and the crash test dummy behind the wheel. A quick yank from the rear had him out in no time and the interior dried nicely once the drain plug was pulled from the passenger floor.
