Just an FYI since everyone here sees intent on throwing the numbers around, Attwood propane heaters are actually closer to %60 efficient. Anything over 75% would require a condensing exhaust which is FAR beyond the Attwood's simple design. The RV propane furncaces are very compact and use forced air induction but at the expense of low efficiency. Lots of the BTUS are going right out the exhaust vent.
Also, the main reason the propane and electric cannot work together is that the electric or propane systems alone EACH produce sufficient heat to drive discharge air temps to the top of the safe range. The propane beyond the safe range and thus the need to cycle the burner once up to temp in most installations. These units are air flow limited by the duct work and can only distribute about 15,000 BTU/hr. of heated air.
