If you have a generator at the ready to run a 110v ac compressor, it's cheap enough. Then you have to store it. I'll be ordering the VIAIR P/n 10005 compressor and tank. I'm going the mount compressor in truck bed and the tank might get mounted under bed to frame. Then I'll mount Air Horns and blow the Dumb drivers out of my way...LOL!
