We've been to 3/4 of those places traveling in a rusted out dodge caravan that we used for a camper. Worked great for camping in COE, national forest, blm and a few rest stops and parking lots when camping plans failed, for 40K miles. Setup was gathering wood and getting out the stoves and chairs, so morning cleanup was quick and easy.
edit: Oh, and a few miles west of cadilac ranch we had a tire blow out on 66. The spare was securely rusted in place. Some guy pulled up and helped me hammer and pry until it came loose about an hour later. Lots of good people out there.
