It all depends on what they charge for electric and what you pay for propane. I have seen several formulas of calculating which is cheaper, but the one that I remember is dividing the cost of a gallon of propane by the cost of a kW-hr of electric. If the result is less than 22, propane is cheaper. If the result is over 22, electric is cheaper.
Example 1: You buy propane at Flying J for $2.99 a gallon and the campground charges 15 cents per kW-hr of electric. $2.99/$.15=19.9
19.9<22 so propane is cheaper.
Example 2: You pay $4.50 a gallon to fill your propane tank at the campground, and the campground charges 11 cents per kW-hr of electricity. $5/$.11=37.5
37.5>22 so electric is cheaper.
We usually avoid high campground prices for propane, so the cost between propane and electric is usually fairly close for us; but we like to use electric even if it would be a little more expensive just to avoid the hassle of having to fill the propane tank as often. Not only that, but our electric heater is a lot more quiet than the furnace.
