Have you considered backup power source for well pump -- even if
something you "manually" engage?

I can only think of a generator. But that's awfully expensive for a very
rare event. In the past 30 years, once for about three days, once a day or
so, and a few dozen for a few hours. For comfort inside I use a 12V deep
discharge battery, a fan and a light.

I don't know how big (electrical load) the pump is. But, was
thinking you could use something like an inverter (even one
repurposed from a UPS?). If the load was small enough
(hundreds of VA), you could find a little UPS/inverter that was
powered from a 12V source (like those your deep discharge battery
is powering).

Then, in a prolonged event, you could use the battery *in*
your vehicle to power the inverter/UPS -- and, periodically
run the vehicle to recharge the battery (this is predicated
on your power needs being small/infrequent -- turn pump on
for a minute or so, then turn it off. Repeat. After a while,
run the vehicle for a short time to top off its battery
before continuing.
