I am finally ready to upgrade, I've got two propane burners, one converted keg, and two more on the way. My plan was to buy a three tier shelving unit at lowes that can support 3000 lbs per shelf, more than enough, and thread casters through the feet. Then use half shelves with the hot liquor tank in top, the mash tun opposite that on the second shelf, the the boil kettle on the bottom shelf opposite the tun, under the hot liquor tank, anyone have opinions?
