I don't know about stealth camping ... but when we go on RV trips we sure could use commercial campgrounds with dirt/grass/scrub special drycamping sections where you could overnight in your RV - with no use of their bathrooms/showers/etc. facilities allowed - for around $10 per night. I rarely see a commercial campground without some unkept part of it that they couldn't make a few bucks off us (cheap) $10/per night self-contained RV overnighters. They could even enforce a one night, or two consecutive night, rule to keep squatters out. :C
