Just got back from the dealership. Got done looking at two 2005 chevy duramaxes. The only difference on the exterior that i could see was the hood was raised some,more like the older 2001.They were both ext. cab, but one was a long bed and one was a short bed.Pretty dang nice if you ask me, the hood is pretty sick aswome.

The grill is way different, all slotted out for more air.
