I've been falling down lots of rabbit holes lately, trying to learn as much as I can. One thing that came up which surprised me was reading that running the fridge on propane vs shore power is more efficient and tends to cool quicker. It seems like many people prefer to run their fridge on propane on the regular, even when shore power is available. In your experience, does that seem to be the case? Does the fridge use a lot of propane to run? I'm trying to troubleshoot our Norcold 3-way (it's pooling water in the bottom) and was considering replacing it with just a battery/shore power version if I can't fix it, but if propane is a more efficient method, I don't want to lose that feature.
