Did you measure the height while connected to the tow vehicle? That's the improtant thing. If you did, and it is over 13'6" then you are talled than the national DOT standard. You better be very careful on anything less than an interstate highway. Local municipal and county roads may not always conform to national standards. Pay attention to signage along the roadways, and to smaller fuel stations with overhead covers.
