We run a dehumidifier made for a 1200 square foot home and keep the humidity at 30%. We take all the moisture precautions too like always having a vent open while showering, wiping out the tub/shower when done, etc. That still doesn't prevent the condensation. The only way to stop that is to not have a temperature difference inside/outside and right now its -2 outside so that would suck pretty bad. These single pane windows just aren't made for this type of cold, neither is the insulation in the trailer to be frank. Problem is it isn't feasible much less economical to have 4 inch thick walls with R35 insulation on a travel trailer.
Thank you for your prayers. They're much appreciated. We're blessed to have finally found good healthcare. Can't beat having the same cardiologist as Neil Armstrong LOL.
