I still plug mine in even in the warm months. The temperature differential between the outside air and your Air Conditioned interior can still result in moisture build up. Particularily at night while you are sleeping in the canvas area.
I Googled quickly and am told the average adult breathes/sweats out 700ml per day. So four people, during eight hours of sleep, emit just shy of 1 Litre of moisture. When you create a temperature differential you can easily exceed the Dew Point and that moisture naturally accumulates on cold surfaces... In this case your Hybrid's canvas. That is just from your breathing and does not take into account the water vapour generated by the pasta you boiled for dinner or the hot shower you took before climbing into bed.
Moisture in any form is the greatest enemy of an RV. My little dehumidifier may only be doing a small part in the battle against moisture, but I will take any advantage I can get.
