+1 on having a weather station / humidity monitor inside your RV. I have one in each of ours. About $12 on Amazon.
If you have continuing high humidity or need to store your RV for awhile, open up your cabinets and put one Damp Rid each in the bedroom, bathroom, and living room. We're pretty humid where we are and each Damp Rid lasts about one month.
