USA country road trip?

Y’all! So listen I was thinking of taking a year long road trip around the USA and hitting up destinations I’ve been wanting to see foreverr! I’ve saved up around $20,000 and counting for anything I need. I’m 21 and very sheltered so this is a little spontaneous and scary but seems like a risk I’m willing to learn from. I was thinking going either solo or a female travel group? I need any advice good and bad. Whether I should do this at all. Or smart ways to go about this and conserve money and safe spots!! Idk gals help me this is definitely I was gonna do one point of my life so why not now!?

Edit: After some thinking yes solo isn’t the best route but I don’t have any available individuals that I know that can do this with me since they’re caught up in their own lives. So I was thinking of joining a certified female traveling group and that way I’m safer. But I do need a flowing income while I travel. What sort of jobs would best suit this kind of life?
