Condensation problems

Hi. My husband and I just bought a Cougar 26rbs and we are.enjoying our first trip. Has anybody had a problem with condensation in the front window (bedroom)? We woke up with some drops falling from the frame, and there is water between the window and its frame....this is our first trailer so we are just learning...

Welcome to the forum. Condensation is inherent in a trailer if you don't have any exchange of outside air. The window over the head of the bed will react to the temperature difference from inside and outside first as you exhale just below it. It's just like exhaling on a mirror or window, it "fogs" up. You're in a small space breathing, bathing, cooking, perspiring, etc. That humidity needs to be exchanged so open a ceiling vent or window a bit to allow the air exchange.

Welcome to the forums and congrats on your camper purchase, and on your first trip.

What you are experiencing with condensation is very, very common with RV's, pretty much all of them. Think of a cold soda can in the refrigerator and then you take it out and it's 80 degrees. They sweat almost immediately. The same thing is happening inside your camper. And the greater the temperature between the inside and the outside, the more they sweat. (condensation on windows, sometimes even walls, under mattresses, in cabinets). Also, the more humid the atmosphere is, the worse it gets also.

As stated above, cooking, bathing, even breathing releases moisture in the air and it has to go somewhere. The water vapor will settle and form drops. When enough forms, it drips.

About the only way to prevent condensation is air exchange. And doing so, you will be fighting cold air coming in, running heat inside the camper, and a constant feeling you are burning through a lot of propane. Cracking a window or several windows and running a fan inside the camper to circulate air and to retain a consistent temperature throughout camper is about the only way.

Depending on how your camper is built, how many places are not sealed tight, where are there are cracks and holes (like around slides, where pipes come through the floor, and electric line holes in the walls) will allow some air to breathe in and out. But almost always that's not enough. You may also need to run your ceiling vent fan to pull air through.

But that is the answer, circulate air in and out of the camper.

RVs, they are that way, not like a stick built house. Use some common sense to create air flow. No need to open a window next to your bed.
Example could be open the bathroom vent a little, leave bathroom door open unless in use. Open a window a small amount in kitchen and then air will up draft up and out. When cooking, using water, the shower etc. open open open a vent. You need to try and find what combo of windows/vents and how much open works best for you, the trailer and the weather conditions to get the best results. Those roof vents in all of my RVs are open almost all the time to some degree unless traveling to keep dust out. When cooking the kitchen vent is fully open, when showering the bathroom vent is fully open. Normally they stay cracked open 24/7.

We run a small electric dehumidifier 24/7 when camping, especially in the winter. Summer not needed most of the time. It helps quite a bit and collects a fair amount of water. I need to empty it every 4-5 days right now.
