"I like the truck overall and it has way more power than ford and the alison trans. the feature were that you can shift it yourself is very good for trailering. Also the tow haul mode holds back very well. Over well the truck is great!"
"This truck is a pleasure to drive and will haul all day long. We purchased this for towing our Fifth Wheel RV. It does this with no hesitation.
It is a comfortable ride.
The diesel engine is very quiet compared to some and very little odor when running."
"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."
"We have 4 of these duramax, allison trans trucks.We have had no problem with any of these trucks. 3 of the 4 trucks never have returned to the shop for anything except routine maintenance. The power is amazing. The diesel engine really shines for farm work where there is a lot of idling. The fuel milage is easily double that of the gas engine under these conditions.
I will be hard to talk out of buying a duramax for my next truck."
"I tow though the mountains in Colorado all the time and this truck is great towing up the hills and even better going down them. I can set the cruise at 65mph and it will stay between 60 and 70mph going up and down the mountains on I70. This truck is one of the most comfortable vehicles I've ever had."
