If you look up "Nomad Living" on youtube there are a bunch of people doing it.
I've heard them on this program talking about it.
Some use P.O.BOX's
Some use independent Mail holding services.
They use their address. Check into it.
It is possible.

Oops, follow this guy. He talks about having your stationary address. He says his stationary address is in Pahrump Nevada.
His youtube channel is "CheapRVliving"
Ummm, who is she?
