Dual Pane windows Fogging up

[Chainsaw]

We are supposed to have Dual Pane windows, it is my understanding that you do not get condensation on them. Is that right? Or is that in-between the glass?
the temp is dropping to 4 degrees Celsius at night, when I get up in the morning, the windows are all fogged up with condensation on the inside. We set the stat at 69 F at night.

If it's humid inside the trailer, you can still get condensation, although less than with single pane. During our winter camping, we never had any appreciable condensation on the windows. But the air was so dry inside ours that we had to get a humidifier.

On our dual pane windows, we can see the separate panes.

If you're getting condensation on the windows, keep an eye on the bed where it contacts the exterior wall. You may get condensation there. We had to leave an air space at the head of the bed and added spacers on the sides where they contacted the slide room walls.

Condensation will form on glass anytime it is cooler that the air around it, Double pane is for the insulation value and no condensation should form between the layers of glass. If it does then the seal for the double pane is broken. It's no different than the double pane in a residential house.
