I have recently acquired a IH fridge, and am currently designing my build. I am kind of torn between electric or propane. I am leaning towards propane, but I am scared I will be filling my tank every 2 or 3 smokes. Can anyone give me a rough estimate on how much gas I would go through? I understand it depends on smoke times, but even a close guesstimate would be helpful. Thanks in advance for your help! Just finished my UDS, and well I'M HOOKED. A fridge smoker is my next toy!
