I always thought about installing an ac convertor in my van. They have them in rv's and trucks, you always have a tank of gas. don't know how many amps they put out but I'm sure you get rig up what you want. My neighbor has a generator and it's a real hassle dealing with 6 5 gal cans of gas. He has to rotate the gas so it's fresh.
Personally, I wouldn't give a two extra shakes of my d%$k after a piss if the whole northeast from Maryland to Maine fell into the Atlantic Ocean never to be seen again. However, I find it ironic when I think of all that global warming those people are sparing the globe standing in line to buy gas instead of burning it. I mean that's the agenda of the people they vote for; both for themselves and the rest of the country. I don't know what they need gas for they should all be riding around in high speed rail, riding bikes, or driving around in chevy volts. Hypocrites. Let them stand for years.
