RV LP Furnace Efficiency?

I'm trying to find the actual efficiency rating of our Suburban RV furnace... but so far have found no published specifications.

Anyone have the real world efficiency rating of the typical RV LP furnace... I'm guessing 70 to 75%.

I'm trying to compare the cost of electric heat at 13 cents per kilowatt hour vs LP at $2.79/gallon and assuming 75% efficiency.

Using the link below... LP @ 2.79/gal vs 13 cents per kW hour... its less expensive to heat with electricity.

Electric vs Fuels - Comparison Result

Electric:

Electric rate (per kilowatt-hour) = 0.130
Cost of heat (per 100,000 BTU) = 3.81


Fuel:

Propane cost per gallon = 2.79
Burner efficiency factor = 75%
Cost of heat (per 100,000 BTU) = 4.03
