We have a 500 gallon buried tank, so it gets filled to 400 gallons. I
think our genny burns about 1.75 gph at half load, so at any time during
the month between tank top-offs, we should have at least a week of run
time, probably more if it is winter, because the larger of our two heat
pumps primarily runs off propane anyway, so if the power goes out, the
only additional load for heat from the generator will be to run the
compressor and furnace fan. The smaller heat pump is not on generator
backup.

... but your gas assisted heat pump is sucking propane out of your
generator fuel tank.
I agree with Dick, "feeding the monster" can be an issue in a long
outage. That term came from our Punta Gorda friends who were living on
a generator for over a month after Charlie.

My wife was prairie building when she brought her community out of the
ground and they ran the construction trailer off of a 36KVA diesel
genset. They got fuel delivered a couple times a week.

The gas assisted heat pump, the water heater, the fireplace and the
stovetop were why we installed the propane tank. I'm not concerned about
running dry because the supplier is on top of things.
