Condensation

[John68]

I have a 2018 Wildwood 27dbk. I am spending the winter months living in my camper till I buy a home. It's in northwest Indiana near Chicago. I purchased a Pelonis 30 pint dehumidifier to take care of the humidity inside. Works great , but I noticed while changing my bed sheets that there is moisture on the wall behind the mattress. How do I stop this ???
I realize this camper isn't made for very cold weather but I have no choice but to live in it. I don't want the moisture to create mold or water damage to my walls either.
Please , I am open for all suggestions.

I cut a piece of reflectix insulation to fit between the mattress and the wall.

You might also want to move that dehumidifier closer to the bedroom wall. Also if you can, put a space between the mattress and the wall to increase air circulation in that area.

I run air circulation fans (3) all the time with heat or ac along with a compressor type dehumidifier

Get a foam pool noodle and put between the mattress and the wall to leave an air space. Also occasionally check under the mattress as the area underneath (storage) is usually cool/cold.
