"Well built, comfortable truck with strong towing capability. I tow a 42' fifth wheel and this truck handles it with ease. Impressive power and fuel mileage averaging 16-17 mpg highway when not towing. Excellent for a 4WD crew cab dually. Lots of useful options such as bluetooth. Best truck that I have owned by far. Have had Ford super duties and before that Chevy's."
"This is the second diesel chevy i have owned i traded a 03 for this 07 classic.
To date it has proved to be the worst truck deal i have made. It was easy to get 18 to 21 mpg in the 03 and the 07 is lucky to get 14. don't get me wrong the 07 out preforms the 02. But when you add up the loss of fuel econmy and the rising cost of diesel it is about to run me into the poor house. The problems i have had have been minor."
"Great truck, use to pull a 38' fifth wheel coach that weighs 15,000lbs. Averaging 13 mpg while pulling at 60 mph and average 18 to 20 mph without coach on highway travel. Very comfortable and powerful. I recommend in a heart beat."
"this truck is the best truck i have ever owned. It has great power, it always starts at 9600 foot altitude, even when its cold after snow. It is the best diesel to date and quiet. the transmission is great but could shift down quicker, the trailering button is great. this vehicle is super quiet and super comfortab and rides like a cadillac even though it is a one ton truck. pulls trailers, including my 40 foot fifth wheel like it is not even there."
