I’ve just noticed that a few states consider a 59’6” trailer as legal, and a few consider structural items as exempt from Permits, IL, TX, OK for example - (though MO throws a wrench in the works).
Case study. 58’6” tubular product, WI- TX, $5/mile, requires Permits in WI & MO only. 1100 miles, 2 days work.
Since I’ve had the stretch, for a relative new comer to OO and platform, the opportunity for minor increments in length has yielded far more than regular 48’ trailers and width. ( Aside all step/RGN etc).
Just like to throw in the alternative thought patterns @Pedigreed Bulldog
