Preaching to the choir here, but the confusion in the government folks still exists. If you DO hit the scales, they look at you like you are nuts for being there and wave you on. And depending on which Highway Officer you talk with, you get different stories.
I have zero problem with following the laws if the laws were clear enough and consistent enough for everyone to follow. The same ruling should apply to the bus conversions and the huge motorhomes, not just the folks trying to do a better and SAFER job of hauling their trailers.
Require a CDL for our rigs but make the air-braked, 50 foot motorhomes do the same.
