Ok. I already have 3 refrigerators, and I'm still a couple years away from having a building with a walk in cooler on our farm. However, I currently have an opportunity to buy some very nice 4 ft sliding glass coolers for $200 ea. Is anyone familiar with these for farm produce? Do they work well, are they energy efficient, and is this a good deal? I run out of fridge room every year, and with the addition of many more fruit trees, I definitely will need the room.
