It's possible if you stay away from hotels, restaurants and c-stores. I spend about 50-60$ a day with a mix of free and paid camping and 1-2 rooms a week. I also have about one restaurant meal a day (usually breakfast). I travel alone and smaller food packages are more expensive. I'm in Canada and things are more expensive here as well. Free camp where there's access to water so you can swim or give yourself a good sponge bath.
