Road trip

I think the wife has been watching too much RoadKill on YouTube. She’s a real car gal. Anyway she wants to take one of the hot rods to the Gulf Shores when it warms up. Straight down I-65. 6.5 hours in a 4 speed Smallblock Duster. I searched on here to see if anybody has made a trip kit. I didn’t find any. I know not too many take real road trips... but we want to. Besides the obvious spare gas, some rando wires and wire kit , alternator, belt etc.... what are some good items to bring that one might miss?
A couple ballast resistors, a spare ignition box, oil. And food and water. That way if you're stuck along side the highway for any length of time, you've got snacks. (And if you have your carry permit, and if it's recognized by other states, a pistol or three)

I know you're wanting to go down I65 but to me, that's not a true road trip. Speeds too fast to really see America. Why not take US 31 , runs nearly the same path as I65 and ends in the Gulf area as well? That's where you'll find epic views and sights more so than taking 65. My wife and I took 65 all the way down to the Gulf in 2015. Was pretty boring until we got off of it in Alabama to make our way to Destin.
