You might consider reading the attached thread, as I will be traveling from DFW to Savannah and SC, returning through NC and Tennessee.

I plan on driving around 400 miles a typical day, will be stopping at Marietta, GA Service Center to top up.
Yes, there will be about 8 hours each day reading, maybe catching u on email, etc.
There are multiple threads and a couple of blogs about planning successful trips into the wild: you can do it, it just takes a bit of pre-planning and patience.
Burlington NC Supercharge station should be on-line in two weeks or so, and I intend to use it at least twice as I go to and leave Durham.
Have a back-up plan at the ready.
What direction will you be coming from?
Do you have single or dual superchargers?
RV Parks with 14-50 outlets for supplemental charging, maybe a Nissan dealership or two and sleeping @ hotels that have charging will be my primary tacts to accomplishing the trek to and from.
Plugshare, Blink and other charging stations as need be.
Feel free to PM me for further specific resources.
