This is my 3rd Duramax and they never cease to amaze me. They get better every generation. Im a farmer drive around 1,500 to 2,000 miles a week on probabaly 75% gravel roads and my previous ford and dodges couldent handel the roads or the mud i travel in. My Duramaxs have had the smoothest ride most comfertable to drive and in my opinion the best for pulling because of the allison transmission. Farmers are probabaly the hardest on veicles and the 2010 GMC 2500HD with the Duramax and Allison can definatly stand up to the chalanges i put it up to and my lead foot probably doesent help either.

I wrote my first review in June after trading in a 2004 F-150. It has only got better and better. Absolutely no issues. Fuel mileage has gone to over 23 MPG on a recent hiway only trip of 600 miles, to between 15-18 MPG back and forth to work and weekend trips. I have not had this kind of acceleration since my '61 Vette'. There are no rattles or any fit/finish problems. Only oil changes and tire rotation. I would not trade this truck for any other on the market. I did extensive reseach and I am so glad I choose this HD2500, Duramax/Allison. I would recommend this truck to anyone, no hesitation.

A refined, well built truck

Well designed, well built truck that is a pleasure to drive, but it struggles to pull my small 6000lb 5th wheel trailer over some moutain passes. ATF temps up around 215 deg although total weight well within published rating. Front end styling is ugly.

The fuel economy of this truck leaves a lot to be desired. My truck is GPS'd so I am only able to drive the speed limit without getting in trouble. The best I have ever got for fuel economy is 14.8 mpg (imperial gallons). The quality of the truck is less than desirable. In cold weather (less than -20c) the back doors will not latch completely without slamming them hard. I actually knocked the molding off the door trying to get it latched. When the doors are closed they squeak and rattle so bad you have to turn the radio up. I have had to install a second battery to get the truck to start after sitting for more than 3 days. The airbag computer already stopped working and needed replacing.

I think it is a very good truck. But I can tell you I think a tin can has more thickness than the sheet metal used on this truck from past years. It is so thin I am amazed it is holding. I also noticed a lot of the quality is gone everything is cheaply built and poorly attached. Other than that the duramax and allison combination is by far better than Ford and Dodge.
