Sounds like a great trip. It reminds me of my early 20s when I would just take off in my old Ford truck with some gas and not enough money to get back. I'd find some odd job or other legal method of getting food and fuel.
I'd second the ear plugs and duct tape. Driving my 40 from Denver to Moab is a very physical experience.
