Fulltime RVer has a post discussing the relative costs of using propane vs. electricity to heat your RV, assuming you have to pay for the electricity. He does a good job of comparing the numbers, but he didn’t consider if your rig has a heat pump, as ours does.
As I recall from my intro to thermodynamics, oh so many years ago, a heat pump typically runs 1.5 to 2.5 times more efficiently than electricity, depending on temperature difference between inside and outside. The heat pump is not turning electricity into heat, but using the electricity to move heat from outside to inside, so it can move more heat than the energy content of the electricity used.
Bottom line, the heat pump will probably almost always be more efficient except when temperatures drop down into the 30s or below.
