I am wondering, with all of the skill available on this board, shouldn't it be possible to redesign a 5 gallon "keg" so that 4 would fit into the Sanyo fridge? Here is my idea: weld a square tube to a volume of 5 gallons, add an opening for a corny lid, and attach the posts. I know this is totally over simplified, but doesn't it seem like there would be a way to fit more than two kegs into that fridge if they were a different shape?
Note: SWMBO has limited the fridge idea to the Sanyo, thats why I may sound desperate. Obviously a bigger fridge is the easy answer.
