This is the beauty of using 12VDC compressed air for winterizing - it only takes 5 minutes for me to do mine. I have done this camping off the power grid over freezing nights and then back to normal the next day... I use the BLOW OUT plug at the city water inlet and blow out all lines - then add a little pink stuff to the P-TRAPS... Also drain the fresh water tank.
On the generator - I just use my 2KW Honda which sits in the tail gate corner of my truck 24/7 to hookup to my OFF-ROAD POPUP where it sits in my yard and re-charge my batteries. I can tap my on-board INVERTER and run a couple of extension cords into the house to run my fridge and and have drops at the home entertainment center and living room area. Gives us plenty of lights, fans. and home entertainment. Charges all of our cell phones and computers. I also have a big UPS unit running for my radio/computer room so this also keeps that charged up. Usually the cable TV and internet also goes out when power goes so I use the trailer OTA antenna for local HDTV. My generator will run about seven hours on one tank of gas. I made it five days running a few hours a day with my 5-gallons of gas on the last 8-day power outage we had. Then I had problem finding a gas station that had power to run their pumps.
We did just fine during the last big storm IRENE. Cooked meals from the patio Coleman Roadtrip - had the patio all lit up and sitting out at night watching HDTV. Mini block party everynight with neighbors coming over...
