This is the 3rd Duramax I have had, none of them have been lacking in power for their tow rating. About 9600 lbs if I remember correctly. Looking at the Chevrolet site, you might be able to get a 3.42 axle option with the diesel. I have just never felt the need for more power and I appreciate the better mileage.
