This was posted on a Cummins forum I frequent. This truck is considered a light-weight as far as diesel pick-ups go while still weighing well over 2 tons. By comparison, my 04.5 Cummins Ram 4x4 quad cab weighs in the 7500lb range. These trucks carry a LOT of momentum with them and tend to take down what ever is in their way when they get out of shape as you can see from the video.
