Keep in mind that every day you have to waste some time to find a suitable camping place that won't get you reported to authorities, find some food, water and perform cleaning/maintenance of your stuff sometimes too.
Create an itinerary beforehand and use a planner like this for maps and notes about stuff you will want to remember while you're traveling through specific areas, don't expect to find a McDonald's that lets you recharge your devices behind every corner.
