Moisture inside interior window trim - normal?

I recently purchased a moisture meter to test my 2014 25' FC. Went crazy with it and the good news is there is no moisture in the subfloor or any areas that seem like an immediate concern.

I did, however, notice that there is moisture (or saturation really) under the interior trim of every window and around the door. I am going to assume this is normal and it's just the gasket that I'm hitting.

Can anyone confirm this?

Thank you.

Having trouble deciding exactly where "under the trim is. If you touch metal, the meter WILL go crazy. It can't distinguish between conductors. Like metal vs. water.

I think what you are experiencing is sweating. Anytime a metal object like a window frame is below the dew point inside the trailer, water will condense. Airstream stopped using double pane windows years ago, so windows can sweat as well. The water will end up under trim and other places you don't want it. A good idea is to use a dehumidifier or winterize and leave the trailer unheated when you are not using it. Warm air will hold more moisture than cold air. Also if you are living in a trailer when it is cold moisture will build up in the trailer from showers and breathing etc. So yes water condensing around window frames and trim is normal although not desirable.
