We do it all the time here in Northern Neck VA. Our power goes out for more than a couple of days at least two or three times a years it seems for us.
I use extension cords for my 2KW Generator that sits secured in the tail corner of my truck.
We only need to supply power to the Kitchen area which has a HDTV sitting area. I will also run a second drop back to my radio room where I have an room UPS unit for the computer and radio electronics.
It just takes about 5 minutes to get setup and sure is a blessing to have my war wagon POPUP sitting outside as well. It has an Inverter setup and I can get a few hours of 120VAC out of it as well running off the trailer batteries. When my 2KW Honda generator is running I can also re-charge the trailer as well..
This has really helped us out having this capability for the hurricane that comes up the east coast. We have had an extended power outage for a couple of weeks a few times already.
We end having block parties as out PATIO is all light and the smell of fresh ground and brewed bean coffee brings in the neighbors. We setup the HDTV and all has a good time.
I have also driven my truck over to help some folks and run their fridge a couple of hours a day as well...
The problem we usually end up having is source of gasoline. The whole county goes off line which means the gas stations are without power as well. You have to find the gas station somewhere in the county that has generator power running their gas pumps hehe..
PLAN Bs even work here at house...
