I'll only buy Duramax

This is by far the greatest and most comfortable truck ever made. And if power and performance are what you want then this is the truck for you. The only trouble I had was with the injectors and luckily they were covered by the LB7's extended 7year/200,000mile warranty. Other than that I have never had trouble with this truck. Plus the aftermarket for Duramax's is so wide open to your imagination.

Absolutely love this truck. Will buy one again in a couple years. The only thing I wish GM would improve is the turning radius for the long bed and stiffen up the fleet side metal... leaning against the outside truck bed wall, I pushed the metal in... it popped back out but left a slightly noticable dent. Also interior could make use of wasted space in the dash board below radio with bench seats.

My 2500-HD

I have owned many new vehicles from trucks to sports cars from Prosches (2), Corvettes (2), VW's (3), Fords (6), Dodges (1), Chevys (2), Mercedes, to Buicks (2). I have never owned any vehicle that has given me the driving satisfaction of never having a squeak, squeal, rattle, or mechainical problem: From dealer lot to 24,000 miles this has been an excellent vehicle and I congratulate GM for delivering the value. I gave this vehicle a relatively poor rating for gas economy but I do like the 6000 Vortec engine and I knew the gas requirements before I purchased the truck: I'd buy this engine again gas economy notwithstanding.
