Condensation on Inside of Windows

Hello,

What can I do to prevent or minimize condensation forming on the inside of windows in our TT?

I'm not concerned about when it is stored as we park it in full sun. However, when we are camping -- particularly when we are not running the A/C -- condensation forms on the inside of all windows to the extent that we can't see outside.


Thanks for your help!

I have only one vent that I could open. It's in the bathroom and has a fan.


I have not been opening it except when we shower, etc

Does the water collect in the dehumidifier or does it use a hose to drain directly to the outside?


Where to you place the dehumidifier?


If a hose is used, how is it routed to drain?


Sorry for the death by 1000 questions...

It has a collection tank you pull and dump. It has an auto shutoff if the tank gets full. You can place it in the shower and let it run. Mine is in the living room under the TV. I may try the shower this year.

If you happen to camp off grid the dehumidifier is a wonderful source for water. A simple water purifier tablet and you have some of the cleanest water around as long as you maintain the tank.

100% Agree!!!

Even cracking the ceiling vents 1/4" helps move the air freely.

I recently tested this on a cold weekend at our house. I kept the trailer at 70 and outside temps were in the 30s. I used a small space heater set on low and it only drew 7 amps.

Night 1, the trailer was buttoned up tight with 3 people sleeping in it. Woke up to every window covered in moisture. Wiped them down and dried them during the day.

Night 2, 2 of the 3 vents were popped 1/4". Same 3 people slept, kept the trailer temp at 70. Woke up the following morning and there was very minimal condensation on only 2 of the windows.

The trailer retained heat well but still allowed for enough air movement.

The dehumidifier suggestion isn't bad; however, it is a tool to manage the existing problem. A heater and popped vents eliminates it.

If a hose is used, how is it routed to drain?

I found a 30 qt unit on Craiglist for $20. I overrode the "bucket in place" switch, removed the shower door, and placed it permanently in the shower. This is in the Cherokee 38P which sits in the same site permanently. The unit drains into the gray tank. The gray tank drain is open all the time when we aren't using the unit, connected by a drain hose to the Blueboy. There have been no issues with freezing.

When we are occupying the camper (usually when the weather is warmer than freezing), we close the gray tank valve and let it accumulate. We can then use the water to flush the hose after draining the black tank.

Definitely should have a dehumidifier. Set it between 45 and 55 percent humidity. Cooking, showering, laundry and breathing all put humidity into the air. Too much can aid in mold and warping of wood and to dry will eat up propane during heating. And crack wood.

If your fan is a Little 4 blade "Noise Maker Type" replace it with a Very Quite upgrade fan! Run it on Low with a window just Cracked! Youroo!!

Windows don’t help if the outdoor humidity is also high. Fans only move the humid air around and don’t remove it. Wet bunk-ends on Hybrids and Popups can be made worse by circulating warm humid air at cooled vinyl canvas. Pop-up gizmos only slow the process, as do double pane windows. The only two real solutions are to prevent humidity (shower-house instead of camper bath, hang wet towels outside, cooking outside) or to use a dehumidifier.
