If a tourist ask you where you live and you point at your RV. Then they ask where you're from and you say here for the moment. Then they get frustrated and insist on knowing which town your from as in a permanent city..then you roll your eyes because you know you're talking to a wall. They're just not going to get it no matter how many easy to understand small words you use.
If a state campground needs your fixed address for their computer and you give them your license plate number. Then they want your real address so you give them the camp site number and campground they just issued to you for the stay. Then they look at you like you're crazy. You say "fulltimer." They suddenly comprehend and say "oh I understand now" and proceed to type something mysterious into the computer.
