Moisture building up

I am noticing in this camper that the cooler the weather is out side the more moisture is building up inside the camper.
We have 4 small children so there is a lot of us in there breathing moisture into the air. When we wake up in the morning the windows are soaked, and sometimes dripping. We went out this weekend and the temps dropped into the high 30's. So the heater was running quite a bit. The first night was really wet, the second night I left the vent in the bathroom open a little bit and it seemed to help some.
How does everyone else deal with this moisture problem?

We haven't had a trailer that didnt have this problem some are worse than others. if pluged in to power you can run a fan to help move air if there is no power then we leave all vents open at least a little and then wipe windows down in the morrning.

What I have done to try and reduce moisture, is run the bathroom ceiling vent fan continuous, plus open a window at the other end of the TT about 1 inch, plus keep the heat on as normal. We find this helps, but with single pane windows in cold weather, there will always be moisture on the windows.

Damp rid, vent caps i.e. Maxx Air with a slight crack open and a lower awning type window craked helps. Damp rid makes a pitcher that you can add to and dump as it fills. Keep it on your counter.

Fans and heat help but due to the makeup of a trailer there is just no way around it. All you can do is try to lower to levels.

If it's a season campsite you might try a dehumidifier if it becomes a real problem. Also you don't want to leave your rig stored moist like that over a period of time as mold and mildew can become a problem. We always have the vents and windows craked to keep air moving through it regardless of temps.

Over this past weekend we had the wall of the slide starting to sweat inside of the strage area over the couch. That coupled along with the moisture running off the windows made it for an interesting weekend with the rain and the cold outside.

I may try some damp rid. Its not on a seasonal and I may be winterizing soon. I put the bathroom vent fan on for a short time in the morning to move some of the moisture, but that fan moves way too much air when it is 40 degrees outside. The heater was running non-stop the entire time the fan was on.
I am hoping this is only a problem when we are camping in it?? Will this still be an issue when it is winterized and just sitting there?

Most of the moisture is from breathing, showers and anything the produces steam. After a trip leave the windows open and let it dry out real good before you button it up the season. Yes moisture will build up while in storage from temp fluctuations but not like when your living it. You still should have some type of damp control within the unit to keep it in check.

Also make sure you put the containment unit somewhere where if it freezes and cracks while stored, that once a thaw comes it will not leak and casue damage. A tub, sink or on a floor in a large basin to catch it works best.

We keep the kitchen window cracked just a little. Works for us.

when propane burns ,it gives off CO2 and water
This could be some of the water, if no most of it
as for the CO2 ,it is a good idea to keep a window cracked open
to let fresh air (oxygen) in
be safe.

This should not be much of a problem when the unit is not in use and the heat is not on. In that case the temp inside and out would be almost the same and no one inside so condensation would be minimal. I still leave the vent open when not in use as I have a Maxxaire vent cover. When using the unit there will be condensation on those single pane windows. Keeping a window or two cracked along with the vent open does help somewhat on those cold nights.
