You can use a po bx as a mailing address, but you do need a physical address to display on your license,
No you don't. We used a mail forwarding service that had a street address + box number (like #105) so it looked like an apartment number.
I wrote the WI DMV and asked if this was ok, but never got a reply. They don't want to deal with it.
We were WI residents all our lives until we started full timing a year ago -- then we switched our domicile to Arizona -- mainly because we bought a park model there.
WI's tax rate was about double AZ's + AZ has better deductions. However, AZ does have a Vehicle License Tax which can become quite onerous if you have newer vehicle(s) -- the newer the vehicle, the higher the tax. But the tax decreases by a sizable amount each year.
While TX, SD, and FL are popular full time domiciles, there are other options, particularly if you need individual health insurance. In that case, cross SD off your list.
Finally, if state taxes concern you, figure out what you might have to pay. Most states have their tax forms online.
