I have a dumb question and I swear I'm not trolling.
Coming from the arid west, I don't understand what the issue is. I know from experience that I hate humidity combined with heat (yes, I'm talking to you Florida and Texas), but I don't understand the issue in the winter when it's cold.
We have condensation on our windows sometimes in the morning, but it always goes away once we get up and warm the place up.
How is the humidity affecting you all so much that you need dehumidifiers? What are the symptoms of heavy humidity in your RVs?
