Dorm frig?
Is the picture your galley?(could not post, too big). Then it would seem that Darrel is right, try a 12 volt system in the icebox. Not easy and not cheap however. You would not want to tear up the area under the stove even if a small fridge would fit.Another alternative I have seen is a custom box under the nav table. Beauty is that you can make it big and very well insulated. Just talked to a friend who is doing that. He wants the much more efficient top loading box. He will put the opening inside of the nav table! Under the nav table can work for 12V or 110V.I cannot completely discount the dorm fridge option since I have one. A previous owner installed one where the gimbaled stove/oven used to be. I have installed a two-burner stove over it. The drinks are always cold when we arrive. If just day-sailing the contents will stay cold for several hours after we unplug. I do not run it on the inverter but I could. It takes about 12 DC amps and would run half the time, so about 6-7 Amp Hours.
