i just got mine last week, bought the runner at the beginning of may. i was suprised at how fast my plates got to me. my uncle who bought his runner a couple of weeks before me hasnt gotten his either. weird.
If the dealers are slow in sending in the dmv paperwork your plates can get delayed. Need not worry as long as you have the temp paperwork you are fine. Plus it feels good to drive a vehicle w/o plates Just gives ya that new car feeling!
