We have a small drive-through with very limited space. Currently we have a True TUC-48 undercounter fridge for milk. With just gallons, we can get 26 gallons in there easily, or fit 2-4 more with some work. However it seems like there's a lot of dead/wasted space. We're growing and looking to buy another fridge. I've been trying to get dimensions online, but inside dimensions are hard to find. Has anyone found an undercounter fridge that can really hold a lot of gallons?
