Kind of a big leap from that article about San Francisco being under a shelter in place order and your statement "But very soon any type of RV travel will not only be difficult it may be prohibited". Could it happen? Maybe. Very soon? IMHO no, not very soon.
We just got back from a necessary Costco trip where they wiped every cart for each patron, offered everyone a hand wipe, and limited the number of people in the store so there were no lines at the checkout and lots of separation. We wiped everything down before packing it into the car (ourselves included), same after pumping gas. I watched a young woman come out of the Wawa Market opening the door, then peeling off a piece of doughnut and eating it and it reinforced our idea that we are protecting ourselves from everyone who isn't concerned.
