Gentlemen, I am looking at a 2006 3500 6spd megacab 4x4 Laramie. The truck has group 2bg and 2tg as additional options that were added, do any of you know what these could be ? When you purchase a truck in Nevada and it meets California Emissions does that mean the mileage will suffer?? If I want to install a Smarty does the Calif. Emissions create problems ? What are your thoughts.
Thanks
Thanks
