Kevin,

Most states don't enforce their length limits. Many say CA actively enforces. With tax revues down, others may follow. I read on a generic RV site that TN levies a $212 ticket. It would be good to know if these are moving violations as they result in points against your license.

A bigger concern would be what would happen if involved in an accident.

BTW, many that are towing 4 down full size vehicles are over 65 feet.
