There is just something about a fireplace still running while I'm not in attendance that scares the bajebees out of me. We prefer to use ceramic oscillating heaters. We have traveled in the early winter and have found they are very efficient, even too efficient, having to turn them down.
Now that I have given you my take on the safety issue here is my take on the costs. If you are staying at a RV park short term (not a full time resident) it is likely you will be paying for your spot that will include your water/waste/electric. So with that in mind why would you want to pay for extra LP cost to run your on board heater. You will need the LP Gas for hot water. Instant hot water heaters are absolutely awesome by the way.
So in conclusion there is my take. On a side note if you're boondocking run run your generator, (hopefully you have one) you will need to in for basic luxeries any way. Tons of scenarios that can be debated, but we hope this was helpful.

Well, my dad was a firefighter and saw way too many fires caused by electric space heaters. I would be more concerned about an electric space heater running overnight than running my furnace on propane overnight.
The wiring to the outlets is less than desirable. Heaters can have large draws.

I will say most of the time I heat with electricity, but it is an add-on unit to my gas furnace. I can switch back to gas at the flip of the switch.
I also now have a 12 volt compressor cooling unit on our refrigerator. Safety wasn’t the issue, constant temperatures was the issue. Still love cooking with gas, and if the power goes out flip the switch to gas and stay warm.

Your fears are just different than mine.
