Here in central Illinois only a few places safety test trucks. Any place that test school buses, ambulances, large trucks can do it. We don't have emmissions test but they check for light, turn signals, wipers, horn, and brakes. No big deal because the truck is new. Shouldn't have to worry for six or eight years because everything works. Fifteen years ago the state tested every truck including 1/2 tons. Save your money if you can. I know how you feel about your plate number. I had the same number since 1972 and didn't want to loose it. I also had the same number on an F350 so I transfer it to my new 05 and put any number the state sent me on the F350, so I still have the same number as always. Take care
