Last5 and I play on opposite teams in the same game. I just have to remember the rules for all 48 lower states, 10 provinces and three territories. He only has to remember one rule book. Most things are the same, but some places have a few curve balls to throw at you. Example in California the center of my trailer axles can not be farther back then 40 feet from my king pin on a 53 foot trailer. But on a 48 foot trailer the distance can be 43 feet if my kingpin is less the 2 feet from the nose of my trailer. If I set the center of my trailer axles at the 40 foot mark on a 48 foot trailer i can be charged with having too much distance between the rear bumper and my trailer axles if the distance is more the 5 feet. This rule does not apply to a 53 foot trailer and a full 10 feet between the rear bumper and trailer axles is ok.
