You don't say if you're towing with a motorhome but the North Carolina length law for motorhome/race car tow rigs was changed about six months ago and it now allows a 90' overall max length without any special permits. The text of the new law is below:

SECTION 1. G.S. 20-116 is amended by adding a new subsection to read:
Vehicle combinations used in connection with motorsports competition events that
include a cab or other motorized vehicle unit with living quarters and an attached enclosed
specialty trailer, the combination of which does not exceed 90 feet in length, may be operated on the highways of the State, provided that such transport take place for one or more of the following purposes:
(1) To or from a motorsports competition event.
(2) For trips conducted for the purpose of purchasing fuel or conducting repairs or other maintenance on the competition vehicle.
(3) For other activities related to motorsports purposes, including, but not limited to, performance testing of the competition vehicle.
The Department of Transportation may prohibit combinations authorized by this subsection from specific routes pursuant to G.S. 20-115.1(b)."

SECTION 2. This act becomes effective July 1, 2009.
