Hi,
Here is a calculator to compare costs:

Electric heaters are very nearly 100% efficient. I prefer 1/2 size oil filled units which I can tuck away into otherwise wasted space.
Where I am forced to winter, electricity is included in the campsite. Clearly that is cheaper than paying for propane.
Turn on the water heater on electric as soon as you wake up. Leave it on until after the showers happen, then turn it off until the next needed use. Mine cycles about every four hours, if no water has been used, and runs for about fifteen minutes. Since there are six cycles per day that adds up to 1.5 hours of unnecessary run time.
From water at ambient temperatures to first cycle takes about 90 minutes for a ten gallon tank on the electric setting. It is about 45 minutes on propane and about 25 using both.
Using electricity for space heating can work well. Is your RV 30 amp or 50 amp? If only 30 you may find it convenient to add a second shore power cord.
