Like many, lacking insulation. House built in 1978. We've replaced all the doors, but not windows. We replaced the galvanized steel pipes to PEX, but they weren't insulated and froze when water pressure dropped.
Have 40 gallons of RO water on hand all the time. And I can quadruple my storage with 3 days notice to push to other storage and make more. Have a generator, but its not tied to the house (yet) and 40 gallons of gas on hand. Need to finish some wiring projects in the house so we can blow in more insulation as well.
And just some better procedures for any event, make sure the cars have their tanks topped off etc.
All in all not horrible, but still very lacking.
