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.

Between LP fridge, heat, probably being at elevation, below freezing temps, lots of moisture was in my TT at local ski area. Din not have as many issues using in summer months.

Well a contractor was using a catalytic heater in trailer to keep supplies from freezing. I was doing some repairs on equipment on jobsite, and every time I walked in that trailer glasses would fog up. If that moisture was all coming from me, the lenses would of fogged outside, cleared in the warmer air.
The operative point is he took a separate heater WITH ITS COMBUSTION CHAMBER into the trailer. We have already established that will put moisture into the trailer. It is not something that any trailer manufacturer includes as standard or optional equipment.

I went back to TimetoRoll's post, and re-read it. First couple of times I saw n't that was not there, so my response was wrong.
Anytime you convert propane to heat you put moisture in the air, and remove oxygen from it. So, IMHO, people should not share air in a limited area with any kind of heater for very long at a time. Now there are claims the unvented catalytic are safe inside living space, but I would not bet my life/sleep in the room with one.
(BTW, I know the low ox sensor has shut down my Little Buddy heater, but I will not go sleep with it on.)

I suspected your wrong response was a reading comprehension issue, glad you went back to reread.
Not directing this at Scooby, but many on a public forum, lack spelling, grammar , and reading comprehension skills. Not all members are educated at the same level. While all are important, reading comprehension matters most, before responding. Many times the OP, made by someone asking a question, is vague, lacking needed information, making response difficult, without providing further information.
I think the OP got his answer early on, and good info on propane combustion venting followed.
Marty has mentioned camping in the severe cold, in his trailer, while enjoying skiing with his family. If he had entire family in that trailer, down to zero degrees at times, imagine the amount of moisture created from possibly 6 people breathing. Had to be a fun, memorable, family experience, which is what RVing is all about!

Good points, Jerry.
Adding to this...
There are good ways and bad ways to get one's point across that don't involve bickering like a four year old: "Ya huh!" "Nuh uhh".
I think I deleted two posts in this thread (so far), one that just said "False", which is the online equivalent to "eff you" and another that started with "Wrong." for the same reason.
Most of you are clever enough people to get your points across better than that. Don't let your quest to be right make you wrong.

Thank you for deleting the post where I mis-read, than declared a post was wrong. OTOH, your declaration that I was saying "eff you" is not true. I consider it a invitation to explain why you believe a statement. Anytime my idea challenged, I will back it up with my experience, or back away from it. Much more is learned from the exchange of ideas, than if whoever posts first is declared right.
BTW, I'm truly sorry I did not look back at the post sooner.

Agree with you 100% on the Buddy heaters. We have the Big Buddy and only use it during the day and with a window vented a little. We've never slept with it on.

Thank you for politely telling me that I'm wrong.
I'm sorry though that you missed the opportunity to learn about how people interpret your posts.
At least it should solve one of the mysteries about why your posts sometimes get deleted.

JMO with only a few nights experience in the 30s but RVs are not good places to be in cold weather. Out of the factory they are not made for it.
Cold air leaks in around slides. Walls are thin. Glass is single pane & radiates the cold. Without some serious post construction mods they are simply no up to dealing with the cold.
You can put up a good fight against cold but it will take alot of electricity & alot of propane.
Point the thing south & don't stop until you no longer see bridge freezing before road warnings or no snow blowers outside of Lowes or Home Depot.
