Not sure what your long term plans are, but camp hosting is a great way to get a free campsite in exchange for a few hours a week of work (or volunteer work). If you have interest in a specific state park or national park, fill out an application for camp hosting and submit it. The rewards for being able to stay longer term in these parks are phenomenal. Not only will you be able to enjoy all the "tourist" things, but you'll also get to see all the "behind the scenes" things that tourists never get to see or experience. That is where the real reward comes from.
It does take time to get your foot in the door, and may take several attempts, and the one you finally land on may not be your first choice, or a location you never thought about before. But these are the best jewels to invest your time at. Once they have you, you show them your value, they'll want to keep you forever! It is a fantastic lifestyle! And money saved as there is no cost for the campsite, just a little bit of your time.
