Moisture in bunks

We have a quad slide double bunk - full time with kids currently sleeping in each bottom bunk. We are currently in Portland Oregon, where it has been raining for at least two months. After discovering sopping wet mattresses, we insulated the ceiling of the storage compartments under them and added a wool blanket between the mattress and the wood. We checked periodically, but we just noticed that there is wetness again where the mattresses have contact with the walls.

Any advice?

Are you heating the unit with propane or electric. Cooking, washing and 3 or 4 people simply breathing in such wet conditions along with the cooler temperatures that we have been having will create a huge amount of condensation. It is very important to have good air circulation throughout the unit. The warm moist air inside the unit will create condensation on the wall if there is poor circulation.

I would add a fan in the bunk areas to circulate the air very well and try to keep the mattresses a bit away from the wall if possible.

There must be poor insulation quality in those walls where the bunks are unless you are seeing this in other places as well.

If the storage area goes all the way across and you have the room you might try adding a small electric heater with a fan in that compartment, providing it is safe to do so.

I forgot to mention that we heat wih propane and also use a dehumidifier. I think the circulation is good and we don't have issues anywhere else. We cook, eat, breathe, shower, wash clothes... So it is Lived-In.

Keep a ceiling vent open about 1/2 to 1 inch, allowing some additional circulation. Keep it open 24/7.

But under those conditions it will be a constant fight, be sure to run the ceiling vents during showers, and get as much of that humidity out.

There are those damp ease products, add them to your closets or you may find some green shoes, like green from mold.

You might want to consider wiping down surfaces with some clorox(y) stuff too, you sure don't want to add mold to this situation, that is really snarky.

You are in a tough situation, but, in my opinion, you really need to work on this diligently, run another dehumidifier if necessary, but, get the moisture out of that unit.

Here is an interesting and timely article I read this morning on rvtravel.com. It may or not help you. The material they use is a construction waterproofing membrane available at specialty construction supply places at about half the price I saw listed.

Great information. Now trying to decide if we can make it work with the trim on the bunks that seems to really interfere.

WE are also in Olympia Washington, And had to pull our Mattress away from the wall about an inch and a half. We also had moisture along the wall where it touched. I have only noticed a little since we did that.

We're in Bellevue, WA in a 3750FL. We where experiencing condensation problems in the bedroom closest, and moisture along the wall right behind the bed. We had to buy a portable dehumidifier, move the bed a few inches from the wall, install some Reflectex insulation under the bed and up the wall. Also, we put a couple BoneDry rechargeable dehumidifiers in the closest, just in case. So far, so good.
