Well, here is my status, I received the Coleman Xtreme which I will convert but was also able to get a 10 gallon Rubbermaid cooler fully converted with a false bottom and brass ball valve along with a 15 gallon converted keg with a t bazooka and brass ball valve for a great price. I can therefore do 5 gallon or more in the rubbermaid and higher gravity in the Coleman.
