I saw an camera install where the license plate had a small hole drilled through the middle and the camera was mounted behind it, very clean looking. This was on a Texas plate which has the state image in the center between the license numbers, so it was easy to hide it. Other state plates may not work out as well, but it was a cool idea for a location other than the tailgate and kinda stealthy.
