I've towed tandem thousands of miles, through MO, KS, NE, CO, WY, MT, UT. With my old truck, trailer, and boat I was about 72'. Then I moved to a long bed, probably closer to 75'.
LEO never gave me a second look.
I've never heard of someone with first hand experience of someone being ticketed for over length. Not saying it won't happen, but I don't think it is common either.
You will likely hear some "fish stories", where a friend of a friend's neighbors...... got pulled over. I am sure some of them could be true.
