Frank, 65 feet is the maximum length of truck and trailer you can run without a special permit set by federal standards....and 53 feet of trailer is about maximum length you can pull and then add the truck cab in front of it.
Have you seen those trailers with an axle about midpoint? Those probably run thru or out of Illinois. They used to have a crazy bridge formula for weight distribution. Every state has different laws governing truck weights and measurements and then you have federal rules/regs. It's enough to drive a fellow crazy.
Tags, insurance, property taxes, permits, federal road use taxes and then all the record keeping and reporting of mileage of fuel use etc....I sold my truck and lowboy trailer. It was much easier and less stressful for me to hire someone specializing in moving "super loads" to move my heavy equipment.
About those bright lights...

...DUmmie should have been around a few years back. There was a trucking company here in the Carolina's that guaranteed delivery anywhere on the west coast in 54 hours....and that was with a single driver. Owner of said company ran some first class trucks/trailers and when his drivers complained of people following them with bright lights, he solved the problem. He had all the back doors on his trailers replaced with chrome or highly polished stainless steel/aluminum. Drivers were already instructed to keep their trucks clean at all times so there was no problem keeping them bright and shiny. Nobody but nobody could get close to the back of one of his trucks with their bright lights on...
