Simple Keggerator for my 5 gallon kegs.
100 qt. ez access cooler stood on end.
I ran foam around the cooler top to keep most of the water inside.
This only is used outside, mainly next to the camper. It does get wet underneath but 3 bags of ice in it will last all weekend with no problem.
20 oz. paintball Co2 tank fits nicely inside with a std regulator.
