I bought my '07 classic chevy 2500HD 4x4 short bed in july of 2007. It has the 6 speed allison and LBZ duramax. Let me tell you, this truck has been trouble free 100%. Runs smooth, you don't even know you're driving a diesel. I would recommend this truck in a heartbeat. It's comfortable and reliable, everything I like. You will both like the independent front suspension, lots smoother than a solid front axle. The 5.9 cummins is a lot louder than the duramax, if you like quiet get the GM. If you don't care, the cummins is probably a lot cheaper.
