check with DMV
I looked into this before buying our 260 as I kept seeing this issue popup. The legal limit in some states including mine is 8 feet not 8.5. Getting a permit here is a trivial matter, its a 1 page form you can do it online. NC is supposedly one of the more expensive states, it is $15 for a one way permit good for 10 days or $100 for an annual permit, tow all you want for a year.Having said that, I have yet to meet anyone who actually gets the permit. It is more for piece of mind than anything. I most likely get an annual permit if we start towing on a regular basis, IE 2 or more times/month. Oh yeah, the permits are usually only good for state/fed roads.
