condensation

It depends on the climate your coach is in. If we are traveling to a cool or cold wet climate area i.e. a place with very high external ambient humidity then the dehumidifier runs constantly. This was especially true when we got caught in a bad snowstorm. Opening an external vent won't help much in that case because all it did was bring in cold wet air. As soon as we added the dehumidifier all the issues went away. It was a nuisance constantly dumping the dehumidifier bucket but better than having massive condensation all over the place. When we camped where it was very cold but dry such as NV we had no problems with humidity and we simply opened a vent and exhausted the warm moist air. We have camped all over the western US from AZ to WA and as far east as CO & MT. We had most of the issues in Western WA and OR particularly near the coasts when in very cold (snow or rainy) weather. Note, however all bets are off if using an internal vent free propane heater. I have direct experience with that and it will produce massive amounts of humidity and unless you have extremely low external humidity it can produce major condensation problems. At 75 degrees F the dew point is 45F i.e. if the external temperature is less than 45F and the relative humidity is greater than 35% you will get condensation.

Dehumidifier is the greatest product that I ever bought for my RV. Keeps all that water from going down inside my windshield. I empty one coffee cup or more a week out of it.

WE are on the road year round and find condensation to be an issue in cool to cold weather. To reduce it we always run the exhaust fan when showering and when cooking. This seems to prevent the most serious condensation. If it starts to build up we will open a couple of roof vents and run the fans to clear the air. We have never had the need to run a dehumidifier in our 13 years.

We have a powered roof vent that we crack open and run on low while we cook. Also do this when we have anyone staying overnight with us. Seems to take care of the condensation we used to see.

Hi,

Open a window. Place an electric heater beside it. Crack a roof vent.

In order to prevent condensation the surfaces need to be above the dew point temperature.

We never close the covered fantastic vent in the bathroom. We cook a lot and never have had an issue with condensation.....Dennis

Yes it has and you can read previous posts by searching this Forum for `condensation'. You can minimize the posts by searching only in the Class A forum.

It is not the stove.

cooking and washing that does it. Good advise above

I always have at least one roof vent cracked open. It does alleviate much of the condensation.
