My '78 rockwood has a built-in fridge.The only name that is on it is on the tray inside the fridge. The name is emperial. Does anyone know what brand this is? i googled Emperial refridgerators with no luck. There are no serial numbers on any of the usual places. I would guess that if I pulled it out it might be on the back somewhere, which I really don't want to do. I don't see anyplace to light a pilot, is this possibly an electric only fridge?
