i have a frabill 6gal insulated bucket i use to keep extra's in .i have a 12v cool bubble pump . up front i use a 3 1/2 gal insulated bucket also with a 12v cool bubbles pump. if you want to use a 5gal water cooler they work great also you can get a kit that fits in the spicket !!! you can also drill a small hole thur the lid to put the air hose thur so you can put the lid on the cooler!!!
