George, how many cubic feet should the capacity be? My office fridge is an 80's vintage GE that measures 33" tall, 18" wide and 21" deep. It's used primarily to store 12 oz. beverage cans and holds at least a case. It also has a nice work surface on top.
I'm not suggesting a vintage model for your application, but there are many makes to choose from these days in that same size, although I think I read somewhere that they all originate from a single manufacturer, likely in China. I don't know how they'd hold up outside.
If the fridge is going to be exposed to the elements, be those what they may in the rather weatherless Bay Area, you might look into something from U-Line, which may include free-standing models designed for outdoor use with a focus on beverages, thereby removing things like crisper drawers from the interior layout in favor of providing more space for cans or bottles.
