Thanks for the ideas and offers. Took the tank to Centennial Tap had them check it out. There was a leak between the valve and prv. Seems to be ok now, but I have not left it in the truck since then and it is still presseurized
You had the Powertank on the Rim that day when we popped your tire bead back on with my tank? Hmmmmm, now you owe me two beers!
are not enough for your help on the rim. Thanks again
