So I'm trying to get better stealth camping and need help.

So I'm in Bozeman Montana for work and I'm trying to figure out how to stay kind of closer to the city. I'm not too good at it I've been pretty okayish for 2 months I've only got caught once. But I cannot afford to live here and I'm not staying here I'm going back to Ohio with my apartment after my contract ends. I don't drive I don't have a lot of money
