"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."
"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."
"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."
Pros: "Duramax Diesel Power, great trasmission, hd frame"
Cons: "No 4wd indicator in dash, not enough cubbies"

"And I have owned a lot of em. This truck is powerful, quiet, reliable and hauls our 3500 pound slide in camper with a quad trailer on back with no issue. It returns about 19 mpg highway with the diesel engine and gives 13 loaded down. It tracks and handles excellent. The diesel exhaust brake, new heavy duty frame and bigger brakes and larger heavy springs make this truck truly HD yet still have a decent ride. I have 12000 miles on the truck and have had to return to the dealer only to have a defective mirror heater replaced. At first I thought the urea system would be a pain, but actually it is no more trouble than dealing with window washer fluid. Power is OUTSTANDING and the Allison shifts smooth as glass. Comfort is great with excellent seats, visibility, climate control and audio system. A HD truck like this is not for everyone, but it works great for our needs. I love it."
