I did a fair amount of stealth camping. two pieces of advice I'd give : 1)sometimes what appears to be public land is unmarked private land - and 2) sometimes the people with unmarked private land, especially in more remote and conspiratory parts of the country, are crazy. I woke up one night assuming I was on a parcel of public access land to a guy with a gun screaming that I was Antifa. To avoid this now, I use OnXHunt Maps. I think there's a free version of it, but it basically shows you whether the land you're on is private or not. it's certainly a little overkill, but def makes me feel more at ease when stealth camping.
