Guessing you took I-95 ? Just did the round trip from VA to FL and noted that parts of NC and SC are pretty torn up. Georgia re-worked most of their roads about 10 year back and is IMO the best, but its only about 110 miles. As for towing amplifying the bumps, believe that TT get it worse than 5v'ers. However there are some bad bridge transitions that really bounce things around on I-95...
