Your signage say your in the middle of the swamp so I'm sure keeping the humidity down is a task. The AC's operate easier if you can keep it below 50% and of course molds won't grow if it's cold. Ceramic heaters cause your RV to drawn in moisture (no air flow). I run a dehumidifier when the windows are closed/ceramic heater is on. I have a weather station that tells me the humidity inside and out.
