Even taking the simpler? case of living in three states with housing in each for 4 months each (more like the JF’nKs), it would seem to be problematic.
I have no idea how those RV camp sites work. If you rent a lot for a few months, is that considered your residence? I suppose with no utility bills you really don’t need snail mail. Banking & credit cards can be handled on-line.
Must feel like the pioneers. Do we have any pilgrims on FR????
