I am looking for a 10 gallon conversion package to turn a 10 gallon Rubber Made Cooler into a Mash Tun. I currently have a 20 gallon SS System, but I want a smaller Mash Tun so that I can once again have the option of a 5 1/2 gallon batch. I've looked, but have yet to find a package for this cooler. Any help?
