Dreamer .....,you must be dreamin'. I've been working and installing in Tennessee (state-wide) for over six years. I've always run company magnets on my truck. I've never been stopped for not having commercial tags. Our company has seventy subs, using their own trucks with magnets, and no one has ever mentioned getting stopped over not having commercial tags or a business.
