Overhang: Depends on routing.  10′ is probably not going to be a problem but much more than that is going to create delays.  Over 1/3 of actual item being shipped length is not going to go over real well.  Consider a different trailer is you are time sensitive.

  1. Tennessee has an annual permit that’s pretty liberal and since Tennessee is a ton-mile state, single trip permits are relatively expensive. If you travel Tennessee often, a single trip permit can be issued as an addendum to your annual and save big bucks. The annual is $1000.00 but especially if you haul superloads, this can save many times the cost of the annual permit.
