In response to Alo. I have a Schwinn plastic water bottle holder that I bought at Walmart. It's attached to a piece of wood and has two Velcro straps secured under the holder to the wood as well. The 20oz co2 tank makes the holder stretch outward, the Velcro straps secure the bottle in the holder. I painted the wood black and liquid nailed it to the cooler between the handles. I also cut the wood to be an extremely tight fit between the handles, I had to pound the weed a little with my hand to get it into place.
