One thing to be aware of-- just the general maintenance cost will be higher- more oil per change, fuel filters 2x a year (minimum) always carry a spare fuel filter and the tools to change it. Fuel cost is higher than gas too.
I have a programmer on my Duramax- I went from 16 to 18 MPG with it on the 3rd level. But too, that's in a 1-ton dually crew cab- it scales at 8000 pounds.
