Great truck! The Duramax towed my 31ft Airstream on a 5000 mile trip without any problems. The truck was very stable and had lots of power to spare in all situations. Gas mileage was around 12.5 mpg towing and 17 alone. I hope for better mileage after the diesel gets broken in. I expected at least some problem to show up on the brand new truck but am pleased to say everything is working perfectly.
Power of the Duramax and the Allison transmission - perfect for towing.
The one bad feature in my view is that the 2500 crew cab with short box only comes with a 26 gallon fuel tank. Not nearly enough fuel capacity for a big truck with a diesel engine especially when towing.
