Our Prep for Power Outage in a Little Old Trailor in Eastern Pennsylvania,
Where we would lose water, heat, and cooking ability. (We would also lose refrigeration, but not a concern if our trailer becomes one.
Water: Gallons of Jugs of Water (to flush toilet), Spring Water to Drink, Squirt bottles for rinsing off dishes.
Hot food: to help keep us warm, if loose power and therefore heat.
Stew in electric CrockPot... which is insulated and should keep food hot for 4 hours of more.
Hot Tea, wrapped in my yogurt making 'cooler', so we don't drink cold stuff that will make us colder.
Hot water bottle can hopefully get at least one hot water bottle filled from the water in the hot water tank, before loosing water pressure, to help us stay warm, until the power comes on again.
I think each circumstance calls for different preparations.
