Dont speed, obey all traffic laws, dont vape or puff in hotel rooms, they will fine you. They cant tell your a card holder by plate.
Bring as much foodstuffs from home as possible.
If your going thru iowa I know an awesome lifesaver organic farm restraunt off interstate. Let me know will find info.
May want to hide meds somwhere just in case, surely your not hauling much, so dont worry have fun, youll be fine.
Last road trip we ate like kings. Brought 1 burner propane stove, frying pan, frozen lasagana, cooked burgers, made breakfast at rest stops, had sandwich fixins, homemade cookiesm french press coffee, 1st class.
Wont find any food worth a shit at restraunts no how and its a nice break to stop and make a meal, have a bowl, cheaper, way better.
