  You have evidently never visited Quartzsite, Arizona, Grasshopper.

  More desert than you can shake a stick at, and even "town" has damn
few power sites, hydrants, or sewer hookups, yet the place is overrun
with OFs between November and April.

   I know people with 30+ foot RVs who can boondock for at least 10
days before needing to dump and get water, whilst our Porta-Potti
cries "uncle" after only 4.
