That video has a lot of fluff and not much meat.
I personally would really like to see how they put the frame back together after they took 11" out of the frame. An 05 Durango frame tappers wider as you move towards the rear, and changes height as well, nothing on that frame is straight or on one level. When you take 11" out, the frame mismatch is almost 4" in height and width. My son and I put an 86 Ramcharger on an 05 Hemi Durango and ended up taking 14" out of the frame. A Durango frame is a lot more work then using an earlier Dakota frame.
Of course, they may have thought of something I didn't. The way I did it sure wasn't pretty. That is why I'd like to see they shortened the frame. Gene
