My new POWERTANK setup just arrived the other day...sweet system. Came with a set of 4 monster valves, liquid filled air guage, extension hose, aluminum bracketry, dual guages, tank and gauge covers, etc. This system rocks when you want to air down and fill up in a hurry.
Fabbed up a mount for the bracket to bolt to so that it is kept secure and out of the way when hauling other stuff in the box.
Blasted and cleaned for primer, paint, and bedliner
Holes drilled in bed floor to bolt bracket to, was sure to locate the underside braces before drilling and then finding out I'd have to drill more holes into the bed.
