I have a 1995 F-350 dually, door sticker says GVRW is 4500kg I'm not overloaded on axle weight but am on gross weight according to door sticker usually around 4750kg gross. My registration in Ontario ...
Canadian cvse if they ever pull you over will look at the 3 numbers on your door tag. You are not allowed to be over any of the 3... Period.... Chances of it happening are slim to none....but that's another thread lol
The registration number itself doesn't mean much to them.
