Hi Jeff,
Just out of curiosity I’ve been watching the internal temp now that I changed over to shore power. the internal temperature is rising and is now about 35 F and this is more then I’d expect as it is only about 3 F warmer then this morning. I’d guess my unit actually does a bit better on propane, certainly not more efficient on shore power.
