I am going to build a Keezer from a chest freezer that will hold 4 kegs in it. I am planning on only putting in 3 faucets. Right now I am not if I need a multi-body regulator or how many bodies it would need. I am thinking 4 would be idea so I could set each faucet to a separate psi and use the 4th for force carbing another keg. Does this sound reasonable? Do you have any suggestions or advice?
