Motels alone would take up $60 or more a day, but if you camp most of the time and prepare your own food, you should be able to afford a room and a restaurant meal from time to time. Don't overlook truck stops and health clubs along the way as many will allow you to use shower facilities for just a couple of bucks and there are lots of places where you can camp for a night legally for free. Though it varies, overnight camping is allowed in many public parks in small towns and churches frequently will host travelers if you call ahead. Ask around the local coffee shop and you will frequently find someone who will let you use their back yard for a night. Stealth camping (camping on public or private land without express permission or the knowledge of the owner) while not necessarily illegal, has its drawbacks. Always have a backup plan in case the freebees don't work out. You should also make sure you have enough spare cash to put yourself up in a hotel for a couple of unplanned days in case the weather turns to ugly to camp.
