So far it looks like it will "only" be 75-85mph winds and concentrated toward the east coast, but that could change. If it makes it as far inland as you are, wind damage and falling tree limbs will be the most worry. If you don't have a weather radio, get one with battery backup. Most state parks will evacuate even with tropical storms so have a plan on where to seek shelter. Make sure you have your kit packed and by the door. Remember to get your meds. I would also take blankets and pillows unless you're going to a hotel.
As others have advised, put slides in, fill fresh water tank, make sure you have fuel. List below of other things:
Non-perishable food, such as energy bars
Batteries
Cellphone charger
LED flashlight
Lighter
First aid kit
1 gallon of water for every member of the family for drinking. (use your onboard tank for toilet and bathing)
