i love my pickup, hauls my 40HP massey with bucket and brush hog like it's not even there. with banks big hoss bundle it hauls balls and doesn't think twice. awesome truck wouldn't give anything for it. it's dependable, and with all the mods it catches eyes everywhere i go. as of now, until ford puts out the 6.7L would only recommend a duramax. cummins is good but everything around it is crap and rides like a semi. duramax is king right now. i just can't say how much i love my pickup.

It's a love/hate relationship between me and this truck. I first fell in love with the outside design. The front view has the same appearance as the Denali. It rides high and has a very aggressive look. It has plenty of power and has yet to be challenged by any load have had. The 6.0L is one of my prized possessions. Most of the of the negative comments here should have been expected, I understand. It sucks gas. I'm averaging around 14 MPG. It offers a bumpy ride. The dash board seems cheaply made, with thin plastic. The rear end can get loose quickly on wet surfaces. The power steering box went out twice. 17 inch rims on a truck of this size is an injustice.

I have had several of the old classic 2500 4WDs and this one is by far the best truck I have ever owned. The styling is so much nicer than Chevy. Only one little problem with the transmission so far. All my previous GMCs spent a lot of time in the shop for warranty work, but not this one! Build quality seems so much better now.

Good, but not great

This diesel was an upgrade from a gas Dodge RAM1500. Pulling a 7,000lb trailer now seems effortless. Turbocharger takes a long time to engage and gas mileage wasn't as good as I'd expected for a diesel- about 12.5 pulling trailer which is disappointing since over 20 without. Just had 3 injectors replaced under 100K Duramax warranty which I believe was a known problem in all GM diesels from 2002-2006. No recall, of course! No significant change in power or mileage with the new injectors. I hate that GM always adds a $95+ "diagnostic fee" for the computer hookup with any service. Also- computer's trip timer hasn't worked since purchase and the stereo speaker sound is absolutely awful.

I have the Duramax/Allison combination. It is a very sloppy running engine. Sloppy in that it is not efficient at burning the $3 plus/gallon fuel it takes to run her. She smokes and run your finger on the inside of the tailpipe and you'll see what I mean. My guess is that in the hoursepower wars, GM spared no expense in trying to get ahead of the competition. They should have left the 0-60 nad quarter mile bragging rights to a more appropriate vehicle like the Camaro or Corvette. I'm looking for a new owner for this one.
