nice rig!!If your not pulling heavy or working with it, the 2500HD is just a $10-12k upgrade for the 6.6L Duramax and Allison transmission. The rest of the truck is the same inside. It'll really be interesting to see the ride quality vs ZR2. It'll be tough to match that.
I just did 1660 miles with my Duramax pulling 12.5k lbs at 75 mph and it didn't hardly break a sweat except on a couple 6% grades. It's very impressive when it comes to working. That's my boy running I25 south of Colorado Springs. It's soon to be his rig.
