In colder weather, you need to ventilate the interior to remove moisture laden air. If you don't, you can end with issues like mold, rot and delamination. An electric dehumidifier may be needed if you plan to use your camper often in cold weather. Cracking vents and windows and/or running a fan means you lose some heat. Don't seal everything up with in an effort to retain heat.
Very true of the propane furnace, which can put out a lot of moisture. An electric space heater will actually dry out the area, not introduce more humidity.
How does a furnace release moisture inside? The combustion exhaust and intake are vented directly to the exterior.
There is a tremendous amount of moisture released into the interior air from human bodies, cooking, showering and from pets. One human body alone on average release 5 cups per day into the air. No difference with electric heat or a furnace, there's a LOT of moisture that needs to be expelled somehow. An electric heater doesn't remove moisture. Remember, the warmer the air is, the more moisture it will hold so as an electric heater warms the space, the higher the RH will be (unless moisture is getting exhausted out).
