I'd throw in 14mm and 17mm wrenches just to be sure.I would drive it if you have the time. Double check all the usual stuff like fluids, belts and hoses. Get the AAA Plus coverage that includes tow service up to 100 miles, some 10mm and 12mm wrenches and a few spare parts. Fuses, belts, oil... Looking at that engine bay Id want to carry a few extra feet of vacuum hose.
Check out @hecrod 's thread Across North America in 5 Weeks, its a great read!
