i own one it has 24000 miles on it and have already had the 3500$ transmission replacedat less than 15000miles and it is a gas hog less than8mpg 10mpg at best,only thing good about it is the manual shift transfercase,one more thing dont drive this truck in more than 8inches of water ill mess the transmission up chevrolet web site read "do not drive z71 truck in water deeper than the bottom of the hubs" n plane terms no deeper than 6-8inches of water for there best off road vehicle, would not have bought this pos if i knew that. Oh an gm doesnt honor there warranties,looking at a new dodge right now to replace this thing with

Very impressive truck, leaves nothing to be desired. Duramax/Allison 6 speed rocks, pulls like there's nothing back there, awesome, what a truck. I got stuff I didn't know they put on trucks, I'm a happy camper.

I own a 08 Chevy 2500HD 6.0L. I was tired of fixing my ford's all the time so I bought a chevy this time around, and I must say I am Impressed!! It rides, drives, and pulls better then my V10 ford did. Plus I really like the look of the new chevy trucks, but it is a gaser so it's not as strong as the dmax would of been but when I bought it a year ago diesel was almost $4.50 a gallon plus it was $8,000 cheaper to buy the gas engine!!But i must say that 6 liter with the 6 speed tranny is very capable of towing heavy loads. I use it to pull my 28' goosneck flatbed and I put about 9 cord of wood on it's back which in the Colorado Rockies is about 11,000lbs and it pulled it convincingly. So with that being said i am very pleased and will buy chevy's from now on!!
