The statement LP gas heater creating moisture may be a generic statement. Yes, if a LP heater with flame vents directly in the room, then I can see this. However the Attwood Hydroflame furnace in our TT’s uses radiant heat inside the camper. The flame heats up a metal chamber, the flame then exhausts directly outside, the heat by way of a blower blows the heat over the chamber and then blows it inside the camper. I may be wrong, but I can’t see how the Hydroflame by it self would create moisture inside the camper. If someone can explain how, it would help as the way I’m seeing it, it does not.
Electric heat would be the same as radiant heat from the Hyrdoflame furnace if I have the above statement correct.
The biggest source of moisture I have found inside is us. Meaning the merry campers themselves. That is not baring some cooking or steam from the cooking/washing/showering.
If I do not vent the camper well, trapped condensation will come. On the windows, unless you cover them some how, they will sweat. The cold out side, hot inside it will condense on the glass. I use the clear shrink wrap plastic to keep the windows in check and then vent well at night while sleeping and the moisture problem stays in check. Vent well means the roof vent a full 1 inch open on the non hinged side, or a side window by the sink etc cracked a good 3/8” open. Yes heat will go out the hole, but so will the moisture that is inside the TT just dying to get out.
I’m not a physics major and may have a few things mixed up, but that was what I have found out.
Hope this helps
