It may seem a little confusing but the state that you choose to be a resident of will not require you to actually live there.Uncle Sam will need you to have an address,if only to send you tax information.At the end of the year Soc.Sec.
will need to mail you some paperwork.Pretty near impossible to be completely "off
the grid" if you have any ties to government programs.IE drivers license,vehicle registration, Soc Sec,Medicare etc.Be sure to do the research,get all the ducks in a row,before you drive off to your new life.
