South American here, gotta my US visa this week, and now I'm thinking about homelessmaxing so I can save on rent.

My initial plan:
>5$ P.O box
>15$ planet fitness membership for shower/bathroom/exercise
>40$ self-storage for clothes and shit
>get a night shift (preferably shit like Walmart stocking/unloading so I don't have to interact with normies)
>live in a big city with a subway system so I can sleep in the subway during the day (the subway system where I live is constantly looping, and if one train is going for repair or something they check every seat for people sleeping)

Thoughts? The only problem I can imagine is if the distance between storage/work/p.o box/gym is too big, then I'd have to be in a developed city that has those almost free public bike rentals
