I have just returned from three weeks camping along the west coast of Baja Sur. I used the Viair I have mounted in the cargo area to refill- it doesn't take up much space and never runs out of air. I would like to connect my rear bumper (tube steel) as a tank. My goal is always saving space. Never used Co2 but long trips and a big tank nix it for me no matter how fast.
