"Excellent truck, great for towing. The Allison transmission alone sets this truck above Ford and Dodge. Very comfortable, pretty good mileage considering (I avg 15.6 mpg when not towing), too bad they raised the price of diesel way above gasolline."
"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."
"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."
