I highly suggest moving your coach to where there is electricity and buy a dehumidifier! Winnebago's have windshield bracket moisture problems. Moisture dripping down from the inside the coach down into the windshield brackets. This happened to my coach and I used some of the methods that were suggested to you to no avail. I finally had an electrician install a 50 amp plug in next to my house. I have a expensive windshield bracket repair coming up in the future. I will not own a RV anymore in the Pacific Northwest without a dehumidifier.
