Humidity in trailer

First off - Happy St. Patricks Day to all!

Was talking to several people here in the park in Osoyoos BC. about the humidity in their trailers. We have no problem in our Sabre 5th wheel, but others have. Several have de-humidifiers. One couple said they pull up to a litre of water every 8 hrs. There's even two identical units where one has a humidity problem and the other does not.
Any thoughts on this?

Controlling humidity is a constant battle. People breathing puts a lot of moisture into the air at night, as does the stove, shower, etc. They could also have an issue if the unit is buttoned up really tight. Good air flow is a requirement.

Some peoples like to create humidity in their trailers when it is cool outside and for a similar trailer you can have a degre of humidity different. Exemple: if you dont create some ventilation with all the windows closed or leaving your ceiling ventilator closed you can create a high amount of humidity inside the trailer. Also if you boil water on the cooktop it will rise your humidity by quite a bit.When you camp in the cool season it is a good idea to keep your mattress a little bit away from the wall also to prevent the humidity and leave the air circulate.

most cases of humidity result for owners buttoning up their RV tight and not allowing for any air movement. couple that with people inside and cold/moist outside and the result is condensation inside the RV.

Maxxair covers on every roof vent & leave the vents open solved our humidity problem two RVs ago. Presently we are using Maxxair IIs on our current rig. The vents have remained open since the day I installed the covers.

2X on the Maxxair covers. My vents stay open all the time. I also bought some rechargeable dehumidifiers. It gets very humid here in the summertime. These are great! Just watch the color of the crystals and recharge when necessary. They are supposed to be good for 10 years! The price is great also. I bought 2 for my 33 ft. TT because with the slideouts in, the door to the bedroom has to be closed. So I have one in the kitchen and one in the bedroom. Love them!
