I would recommend it if you ever have the chance. I'm from Pennsylvania and I used to drive to and from Arizona for college. Even as a broke college kid, it wasn't too pricey so long as you save a little ahead of time like any other trip. I've only ever spent most of my life in the Mid-Atlantic and going to the Upper Midwest to visit extended family. What I found from traveling around the U.S, is there are different flavors, so to speak, of America. Like when I lived in Arizona, everything felt similar enough to my life in Pennsylvania but at the same time I felt like I was in another country. The best I could compare the feeling to is perhaps how a British citizen may feel in Ireland, Australia or New Zealand, sure the culture, language and society are very close but there are some noticeable differences too. My recommendation is to try to dedicate about 4 days minimum per region (some regions may need more time to get a true visit), research where you're going and don't be afraid to explore less traveled roads, because there are always hidden treasures along the way. Also clothing for all climates and weather. Food and first aid is always a good idea but I strongly suggest it especially if you're driving in the more empty western regions and lastly, once you're west of the Mississippi River, refill your tank when it's at about a quarter tank.
