I already own an 03 2500 hd with the 6.0. It has been trouble free for 106,000 miles. Bought an 05 F-250 Powerstroke and had nothing but problems and happy to say I have traded for the 09 2500 Z71. The truck is tight in its handling. My 03 has 4:10 gears and pulls like a mule. I opted for 3:73 rear end on this one for better fuel mileage. The suspension is tight yet not jarring like my f-250 though both are 4x4's. The back seat could be a little roomier as I have two children in car seats, and with front seat at furthest position the car seats are cramped. It is very quiet whether on black top or concrete and the head room is ample for me as I am 6'4".
The ride of the Chevrolet
Beefier tires and rims on the z-71. Door handles don't allow for driver to ride with left led bent upward.
