How to reduce moisture, condensation inside a car?

[JohnC]

For now the Cheyenne is parked outside until I free up garage space. Winters in Nor Cal aren’t super cold but can get to freezing at night and it’s rainy in the winter.
When I go out to the truck at night there is often a lot of condensation on the inside of the windshield. I noticed some mildew growing on the top side of the visors (cleaned up easily with bleach spray).
Before I start to get corrosion issues, is there a way to limit the humidity inside the truck? Condensation occurs when cold meets warm, so keep kick panel vents open or closed?
Just live with it until I can get it in the garage?
My DD doesn’t seem to have this problem.

Thanks

Damprid is what I use. You can buy it in varying sizes, but I buy the big bags and swap them out monthly.

I would also try Damprid

My Mercedes has the same issue, I think moisture is getting in somewhere.

These electric ones work very well. What I like about them is they evaporate the water . You don’t end up with a tray of toxic water that can stain or ruin your carpet.
