I have a small 900 watt gen. for the camper trailer and a 2,5 kw for a backup when the power goes out to save the 3 freezers. Don't plan to stay in electricity if SHTF scenario comes up. A small solar setup to charge the 12 V batteries for keeping the re-chargeable lights and flashlights going as long as possible tho. Lots of LED lamps, flashlights, re-charge batteries, solar USB chargers and hand crank lights. The rest I will just do without. Only my plan at the moment. Have backup heaters, grills, lighting and such with propane, butane, petroleum and gasoline and the 20 and 50 lb propane tanks are my interim backups. How long they will last is decided on the weather, cooking needs and how much I plan to work in the dark times...
8 plates of window glass which are 5 mm thick and 20 inch square which I can use to build a solar cooker for small meals and bread. A tripod grill and a Weber grill and the smoke house will last long after the gas and electricity are gone, and that rounds the picture off for my needs, I hope....GP
