>shaving off %10+ in state taxes is a huge deal.
Unless you're in CA, NY, HI, your state tax savings is probably not 10%. Sure it can be a fair bit but 10% is way too generous when it comes to tax calculations; always be conservative with your savings. Again rent, utilities, and so on will be far more than 10% on average. I moved from a state on the west coast to North Dakota, my CoL dropped ~70%, sure tax was good but the cost of electricity+rent+food far exceeded my tax earnings. Sure SD is nice, but TX arguably has better weather with no income tax and arguably more to do from November to April.
I would not trust the use random RV or addresses for an address over a PO box you turn in, because especially with a bank, you probably don't want your 1099/W2/1040/whatever going to some random who now has literally all your info to commit fraud on easy mode.
OP just needs to state what he wants to do:
A) See the USA and spend a bit of cash doing so to "digital nomad"
B) Go NEET mode and save up a bunch of cash for a year or two then go fuck off doing who knows what
Trying to do both is just going to end up fucking up and spending far more than you should. Even Extended Stay on month rentals are stupid expensive these days.
