We just picked up our new jayco 26BH and driveway camped the other night for the first time. The temp. outside was probably 40-50s' throughout the night. The heater came on frequently during the night. When we woke in the A.M. the windows were wet inside. I assume it is from us breathing. Is this bad to have the condensation like that or is it normal? If it is bad, how do you prevent it? Any tips other heating and cooling tips?

Thanks, J

This is quite normal. Suggest you open the roof vents a little during the night to allow for some air exchange.

This is real common in cool/cold weather using the furnace. IMO electric heaters aren't quite as bad. It helps some to open an overhead vent some and open a window a couple on inches. Make sure to run exhaust fans when cooking and showering.
A dehumidifier might help.

The amount of moisture that air can hold depends on temperature; warmer air can hold more moisture or water than colder air. Moisture can pass thought most material in your RV except glass or any vapor barrier that the manufacture put in. The water on the glass you can see, that in the walls and ceiling you can’t. Single glass is not a very good insulator, duel pane is better.

If you have a lot of moisture over a period of time it can create problems. The best solution is to vent the excess moisture out. Opening a vent or window will help, or you can buy a dehumidifier for those times it’s a problem. The cheapest way would be to just crack a window or ceiling vent.

You will notice less if you keep the blinds open.

Roof vent is best to open a little because the warm air, which is holding the most water vapor, rises and exits.

You're getting good advice about opening the roof vent to let the condensation out, but what about when it's raining?

The best thing I ever did was install roof vent covers. Now I leave my roof vents open even on the rainiest nights and we have no condensation inside the trailer in the morning. Before I installed the covers the inside of the trailer windows was always soaked due to condensation. We bought our vent covers at Campers World, and I installed 3 of them in a little over an hour.

I think you were breathing too hard.

We don't open the roof vent but rather open the two small jalousie windows that are up high above the Gaucho bed.

We do have condensation problems when the outside temp drop close to or below freezing and inside the trailer is nice and toasty warm.

This was our first time camping in our 2000 flagstaff TT. It was pretty nasty outside so I was bored and started cleaning the windows and screens on the inside. The black******and mold that came off was just plain nasty. The gook was not even from us. It was laying at the bottem of the windows. It too me 1/2 a roll of paper towels to get it all off. The window trim is black so its not that visable by eye.


The condensation on the windows is what prompted me to clean the windoes and Im glad I did.
