first off the duramax engine is made by isuzu who is the largest diesel engine maker in the world so they do have more experience than cummins, the biggest changes IMO is the frame, the frames were weak design, with a poor hitch design, with these improvements comes new a-arms and i am assuming here that means new ball joints as well.if they can get the box sides to stay on they might actually have a truck
