and you'll only need the temp plates if you have to go an emission test done.
if the vehicle is exempt, or if you get current etest cert paperwork from the seller (this is required, but not always done), you can just get full plates.
also: i wouldn't stress too much. the truck i'm buying in a couple weeks is up in avon, i suppose if its convenient i'll stop in avon and get temp plates, but if its not i'll just drive back here to louisville.
i've made a habit of printing out a sheet of paper with the words "just purchased in transit" and tapping it to the back window. i've driven past leo's and nobody has ever stopped me to saw howdy.
