Just recently my trusty ole ARB compressor has started to fail. It has served me well for almost 10 years now. I had plans on replacing it with the ARB dual compressor but saw a video ad on the Powertank CO2 inflation kit. I figure since the road pressure my Powerwagon is in the 55-60psi range, this might be the faster way to air up on the trail. Now the price for the powertank kit is a little more than the ARB twin compressor kit so I decided I'd give it the old DIY attempt. After scouring Youtube for a couple of vids, I figured I had a solid grasp on the process. A friend just happened to be selling a full 20lb bottle so I snagged it. It has a preset 150psi regulator on it so I just attached a quick disconnect air chuck to it a bam, for less than $100 I'm in the game. I may add a pressure gauge just so I can verify the regulator. The 20lb should last me for a bit but I'm thinking of downsizing to a smaller bottle down the road. Now just have to figure out a mounting bracket for it. If I go with a 10lb bottle, it'll fit nicely in my bed toolbox.
