I'll fully admit that I don't understand how the science of things work... but an electric resistance heater will dry the air and you won't have excessive condensation inside the camper. The propane heater doesn't dry the air and its quite common to have excess condensation inside the trailer.
All things equal the relative humidity drops with increased temperature. This is why the cold window or a cold beer sweats. The air in proximity cools and becomes more humid to the point the moisture actually precipitates out of the air and onto the item.
Same effect no matter the heat source.
Unvented combustion of any hydrocarbon produces moisture. Wiki has the chemistry if someone needs to see it.
