I think part of all the confusion around enforcement of truck weights is due to the fact that RV guys falsely tend to assume that commercial truck weights are policed as a matter of public safety. Public safety is only a part of their concern....they want to see that the equipment is properly maintained with working lights and brakes. The main reason for commercial truck scales and weight enforcement is to protect the roads. The size of the tire footprint and spacing of the axles determines what a truck can carry on the road.........they don't care about your axle ratio, horsepower, suspension or strength of the frame..... if I want to wreck my truck that is my business, the police are there to ensure I don't wreck the public roads.
