I come to you master modelers with a question that has been on my mind for years now.
We all know a bumper of license plates and a door of fuel decals were a part of the big rig dress code back in the day, but what determined which plates/decals/sleeper script was required for one’s truck?
Suppose an owner-operator lived in California, and he operated up and down the West Coast and out to the Rockies. Would he need plates/decals for each state? And was the little “bingo board” used in lieu of license plates for states he didn’t frequent as much?
