Along with them, KOA, Passport America, Thousand Trails, and several others have discount programs, but be advised that most will have some types of limitations on the discounts. Another possibility is organizations that have facilities, Moose , or other lodges, Military bases, and the use of the golden age pass are all methods people use to reduce expenses. For extended stays most folks seem to gravitate west for a reason, cost tend to be lower.
Edit add on
Most folks that dry camp/boondock seem to be out west. But there are public lands available in the eastern states for low cost options. Allstays, and some other campground locating apps have information on them. National Forest lands, some state and even utility companies also have low cost, low amenity areas that are available, but are a little more difficult to locate.
