Well I'm back after 4 days with out power. Below is a video of my set-up during Irene and power loss aftermath. In this post I will visit lessons learned and what to do next time here at home.

The emergency plan set-up HITS:

* Jayco 213 Trailer Camper, our life boat. Propane fired hot water, fridge, furnace and range/oven (manual pilot)

* After losing power power I transferred all the food to our camper fridge that is propane fired. However with no generator we lost all the food in our deep freezer after the third day.

* (2) 80 Amp hour battery, ran all the radios, auto-patch for the EOC's for (2) days with out recharge. Had 20M,10M,2M,440CM and scanner radio working.

* Filled fresh water 32 gallon tank two days before storm, water lasted (4) people two day before refilling, in case town water shut off or bad water.

* Auxiliary Anderson power Pole port in Honda Civic Trunk, this provided a way to charge/run Batteries

* Inverter 350 Watt and 140 Watt, Inverter ran TV/DVD and cable telephone PBX / Internet modem

* 10 gallons of gas on hand, power was out for days and the fuel pumps where not working

* Plenty of 9V,AA,AAA,C and D Batteries and flash lights

* Tons of food and water

* 600 Lbs of propane plus (4) 20Lbs Tanks, look into a way to connect trailer into big tank.

The emergency plan set-up MISSES:

* No hotwater in main house (electric water heater), However had hot water in camper, Look into propane hot water heater upon upcoming replacement.

* Generator to run at least the house lights and or deep freezer and or furnace during winter.

* Fast battery charger, when charging from the car the voltage wasn't high enough to quick charge the lead acid (14.4V) look into inverter / 20 amp battery charger combo

* A way to pull up the car closer to the radio shack, currently using 50 foot 12AWG extension cord for 12 volts some serious loss!

* printer that works on USB and smaller power than my laser printer, had to print out a couple of things but the laser printer took too much power

* Cordless phones need power! Look into corded ones and swap them in during storm.

* bigger battery in cable phone PBX, ran ok with inverter but can hack a bigger battery in 4.8AH lasted two days, Also power up WIFI and cable modem.

* could not light oven, electric pilot (used camper oven)
