Keeping the windows clear.

Is there a secret when it's colder outside and you have the heat going? Have the camper set to 70 while the outside temperature is around 40 to 45. Windows are full of condensation and it would be nice to look out and enjoy the view even if it is raining.

Having a roof vent in our bathroom cracked open helps a lot. Also if you use a portable heater to help heat it cuts down on condensation build up.

The condensation occurs because the trailer is a relatively small space and our bodies give off a relatively large amount of moisture when we exhale. Add cooking or showering to the mix and the humidity inside rises quickly to 100%. Since the windows and doors and their frames are more heat conductive, they cool faster when the outside temp is down and thus condensate begins to appear on them.

If it's cold enough outside, condensate will also form on the outside walls and ceilings. Folks camping in spring and autumn weather have reported enough buildup of moisture that it will actually begin to rain on them in the bedroom after a few hours of sleep.

The traditional solution in RV's is to crack a window and/or a roof vent allowing for a slow turnover of the air inside the trailer. It's takes some trial and error to find the right combination for your trailer. Open them up too much and the places gets chilly. Not enough and you don't remove the condensate. If you are cooking, run the stove vent. If showering, keep the bathroom door closed and crack open the vent in there.

Those who have the heating element option on their air conditioners should give that a try as well.

The windows are not thermo panes so you will get condensation on the inside of the trailers windows when using your furnace. This is normal. You need to let the moist air get out so the best thing is to open a roof vent slightly or crack a window a little bit. You will still get some condensation but it should be less.
