I just ordered a 7.2 cubic foot chest freezer that I plan to make into a keezer. I will be putting the CO2 bottle in there, I think it will fit nicely on the condenser hump. My question is this. How many 5 gallon cornelius kegs will fit in the chest? From all the photos I have looked at I believe the answer is 4. But I wanted to check with the experts first.
