I'm setting up a generator for a customer at the moment. They bought it Friday night. Near exact wording was "Here it is! Have fun, electrician will be here tomorrow at 7:30am!" Lots of fun getting it installed, buying all the accessories (yes, generators are not magic power boxes) and writing documentation starting with "If you do this incorrectly, you could kill someone." Do y'all have ANY idea how fun it is to hunt down gas containers right before a hurricane? They got a very nice handy guide explaining what goes where, in what order. Packed up everything nice and neat in a bag too. Spare oil, oil pan, fuel stabilizer, funnels (different colors for oil and fuel), gas cans, cords, cables. Plus inventory and documents.
For myself, I picked up some extra munchies. Tomorrow I will pick up two more cases of beer and a couple extra cases of water. I have plenty of water for drinking. This will be thermal mass. Toss two in freezer. If power goes out, toss one frozen case in fridge. Not ideal, but cheap and can't hurt. I've been eating everything in my fridge for the last week, and have enough dry food to last me several weeks if not months. Comfortably. Theoretically, between multivitamins, protein bars and dry food I could probably last a year at just above starvation mode.
Aside from that... I dunno. Cleaning and organizing? I have batteries, flashlights, food, water, lanterns, etc. I could survive off my hiking/camping gear alone. Only "need" is to sort and organize my gear into being more easily accessible and modular.
Couple more long term thoughts learning from Sandy. I want one small generator and maybe one larger generator. Moreso for winter snow storms. My external garage has a small bathroom that needs to be heated or pipes burst. It's somewhat insulated, but I'll be re-doing it hopefully next year. Doesn't need much. Might rig up a large UPS to run a small heater, use generator to charge batteries.
Main house is oil heated. I have enough oil filled electric heaters for an emergency, but no work with no electricity. Garage has a chimney, so I'll be tossing a wood pellet stove in there but probably not this winter. House would be expensive to rig in a generator. Mentally tossing back and forth on that. Probably just do a stand-alone for fridge and a handful of heaters (to save the pipes).
