Definitely have your car checked out, tires, wheel bearings, suspension, ect. Just in case. I would take atleast 2 empty gas containers and have them filled up when you're getting ready to pass lets say, Alabama. I know I wouldn't want to get stuck there.

I remember when I took my car to Myrtle beach, SC. And ended up having an awesome time. Driving away from home is always exciting and full of great experiences. Good luck and make sure you come back with some sick pictures.
