You have electrical, use space heaters rather than burning up your propane, burn the park/campground electricity instead. Use a couple, just make sure you put them on separate circuits to spread the load out. Cheap milkhouse heaters or ceramic ones. Cheap at places like Ollies. Just be sure and set them on the floor out in the open, so they are not blowing on anything.
As already noted, put a auto trouble light that uses a regular screw in INCANDESCENT bulb in the service areas that have water fittings. You can still buy 100watt "rough service" bulbs, the government banned regular 100 watt bulbs several years back.
