I have always had Ford trucks, except for the 47 Chevy I grew up driving. My brother used to work for GM and I could of bought GM products at his cost for many years. The new Duramax Chevy engine has caught my attention. I can get 18% off what the dealer pays for it so I am thinking about this for pulling my trailer with 2 Choppers and plowing. Is this too new of a truck to buy yet or do you think there are any bugs in it to work out? I realize this is a dumb question, but I know Allison has been around for a long time, but I just wonder about the engine. I had never heard of them before now. It's not to often I ask a question on Lawnsite, so I thank you in advance for any input on this subject.
