I too use Dri-Z-Air in my own trailer during winter storage but I sure don't leave any vents or windows open. :R Hard to imagine how a desiccant which is designed to remove moisture from the air inside the camper could work effectively when an open window and/or vent would allow the free flow of damp outside air into the camper. :h
THIS. Pick a method.....but not both.
Before you park it, run the heater during cold weather.......with just a tiny bit of ventilation. That should dry it out. Then use your chemical descants with vents CLOSED.
