Review
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.
Favorite Features
Nice ride, quiet for a diesel, and handles way more than 3/4 ton payloads with ease. The "trailer mode" works great on hills saving lots of wear on the brakes.
Suggested Improvements
Make a step bar standard- these things are high off ground. Also bigger and better grade tires. I've been through 3 sets now at 66K miles.

Love the truck. Drove the Ford and the GMC and fell in love. Drives sweet. Tow a 10,000 lbs 5th wheel and don't even know it is there. Transmission is great uphill and down. Bose stereo is great. Heated leather seats and dual climate control are sweet. Would recomend this truck to anyone.
Favorite Features
The whole truck
Suggested Improvements
Spruce up the dash a little.

Review
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.
Favorite Features
Appearance from the front. Horsepower.
Suggested Improvements
We need larger rims.

Review
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.
Favorite Features
It'll pull and tow just about anything. It just cost too much while doing it. Great truck for someone connected with Exxon etc.
Suggested Improvements
Build a truck to be a truck and not a sports car.
