I've always read that electrical resistance is the most efficient heat.
But, also the most expensive.

Nope, a heat pump is more efficient that resistance heat. Unfortunately the makers of RV heat pumps are stuck in the 1990's. With the new gases available, and newer technologies, residential heat pumps are still very efficient down to zero and below outside temperatures. Maybe at some time the makers of RV heat pumps, and AC units, will start making their units to be as efficient as the residential units.
Here is a link to one unit that still operates down to -13F. Low temperature heat pump
