Yeah, I think this is going to keep me going for a while! I read somewhere that a 20# tank would be good to carb and push in the range of 40 cornies, so I don't think I'll have to refill this monster for a few years!
I just picked up an 8.8 cu.ft chest freezer last night too for use as a keezer. I think this thing will fit at LEAST 7 cornies, possibly more with a collar.
