Where should I stop on an East Coast road trip?

We are starting in Texas, first day straight to Augusta, GA. After Augusta we are going to take our time meandering through SC, NC and Virginia before we end up in Baltimore and then on to NYC. Any suggestions on places to stop (especially in the SC, NC, VA portion of the trip) What are the best beaches in the area? Any cute little towns or natural areas? We’ll be car camping the whole way so any camping spot suggestions would be welcomed.
