I personally don't feel the need for the level of safety of a J1772.
However, given a few years, the number of people using and frequency of
plugging in to charge must dwarf the number of times people plug in RVs. In
the long run, some safety that doesn't involve your body as a ground fault
detection is warranted.
Incidentally, a year or so ago, i emailed the program director for the
wash-ore I5 ESVE network. They said, i'm pretty certain, the cost was about
$20K per station. I presume most of that is bringing the power to the
location. At any rate, the cost of the connector and contactor is
relatively small. I have no idea how much it costs to install RV hookups -
presumably a lot less. Maybe they are substantially lower power?

conditions, you'll find a pump easily within the amount of range left.
Do you think perhaps that this is the end result of allowing this
idiotic EVSE thing to be foisted on us? I do. What is the cost of a
charging station? $5k? More? What is the cost of installing an RV
panel? $500? Less? What risk has been avoided by using EVSEs? Have
you heard of any RV shocking incidents? At 1/10 the cost (less?) of
installing J1772 EVSEs, how many more RV panels could have been
deployed?
Extra credit question: Which EV manufacturer does not require
J1772/EVSE to charge at high voltage (out of an RV panel)?
