You could buy a Generac generator (either NG or diesel) and have a contractor install it for about a tenth of that price. With diesel, you could have a storage tank, NG you’d be relying on the utility to maintain service (don’t do this in TX for obvious reasons). A 120/240 genset that puts out 100A should easily power a fridge, freezer, 15A outlet, and a/c compressor/furnace fan. Hell, for $65k you could buy a brand new F150 with the 7.2kW generator onboard and install a manual transfer switch and emergency panelboard, and then manually cutover the power yourself by running the truck and flipping the transfer switch. Doesn’t help with a lack of gasoline though.
