Is your budget feeling a bit stretched by the high cost of long-term camping?
Then you may be surprised to find out that there are huge areas of the American West where you can simply pull off the road and camp for free. And when I say "huge," I mean HUGE!
All you have to do is look at your map to find areas marked as National Forest or BLM land, and you'll see that they literally are everywhere. These lands are owned by the Federal Government. (BLM stands for the Bureau of Land Management). And you have the right as a citizen to politely pull off the road and set up camp, so long as there isn't some local ordinance against it. It really is that easy.
Many of the cheap and free campgrounds listed on FreeCampsites.Net are within BLM or National Forest lands. Some are hardly more than a picnic bench and a fire ring, and maybe an "iron ranger" box for you to honorably deposit your small camp fee. Many more, though, are completely primitive sites with maybe a fire ring and a signpost, OR... nothing at all but an obvious clearing where others have camped. But the simple fact is, that if are a self-sufficient boondocker, you don't need to spend any time at all researching official campsites. You can simply drive into a pretty area, find a spot you like, and camp as long as you like.
There is usually just one rule that you should check on, and that is the one about the "dispersed camping" time limit. Typically the rule is that you can't spend more than 14 days in a row in the same spot. After 14 days you'll need to drive to a different location at least 30 miles away until a certain amount of time has passed (usually 14-76 days) before you can return.
Note: Some experienced boondockers will tell you that the farther you get off the beaten path, the less likely a ranger will even know you're camping out there. While it's cool to know that one could actually get away with a much longer stay, I prefer to keep to the "honor code". (And after 1-2 weeks, I tend to get excited to check out new areas anyway!)
