I am planning on purchasing a 2012 GMC 3500 Duramax Diesel SRW Denali from a dealer in the State of California, but do not live in that State. I realize that California has very specific Emission Laws.  My question is this....
Will this truck have anything modified to it, compared to a truck of the same make and model that comes from a state that has a less stringent emission control. Wondering if there are physical changes to the truck.....will there be a change in fuel economy or any other changes?
