2018 flagstaff superlite has condensation on walls

Hi,

Welcome to the forums!

What to do about condensation?

The cause of the condensation is the walls are below the dew point temperature. If the walls can be made warm enough the problem disappears. Running a fan to circulate air may help to raise the temperature on the surface of the wall.

One other solution is to reduce the relative humidity inside the RV.

The easiest way to do that is to open a roof vent a bit, find the furthest window from the vent and open that a bit. An electric heater near the window will improve that and keep you warmer. I'd suggest a low wattage radiant type, or a small oil filled (if the oil filled can be on a shelf so the air from the window passes over the fins.)

I know opening a vent and window when it is cold seems counter intuitive, but it does work.

Another possible solution is an electric dehumidifier--but the cooler it is the poorer they work. They are generally energy hogs, some what bulky and definitely noisy.

The above is from this series of posts under full time RV'ing:

I suggest reading it soon!

Very common and normal when living in a box that has 2" think wall....in the winter.

pianotuna above has some good solutions.

Get and use a BIG dehudifier

The OP said - "also i dont have access to electricity 24/7 so a dehumitifer is not an option".

Just people breathing inside a closed up camper will create condensation so ventilation is a must.

Condensation is your doing, not the RV’s doing. Open a window, buy a dehumidifier regardless of your electricity issue, lower the indoor temperature etc. An RV isn’t a stick and brick.

Things inside a TT that produce water vapor.

Exhaling - the human body expels water vapor while breathing. You can produce a quart or more of water vapor just while you sleep. So figure one person can produce 3 or more quarts per day.

Cooking - moisture boiled off while cooking either in the oven or the burners on top of the stove. Propane combustion also gives off water vapor as a byproduct of combustion. All microwaves are vented at the top rear of the cabinet. Although they are usually mounted over the stove hood in trailers they are never vented by the stove exhaust fan. The microwave exhaust usually winds up coming out of the grill at the front top of the cabinet enclosure the microwave sits in.

Propane heaters - Mr Buddy, Wave 3, etc all will add to the humidity level due to combustion.

Showering - hot water and cool air means more humidity.

I normally kept both roof hatches cracked about an inch. When it was too breezy or cold and I had to close the front hatch I ran a 25 pint per day whirlpool humidifier set at 40 percent humidity. That was suitable for me and one Chihuahua in my 28-1/2 footer.

You can open the rv vents and windows for ventilation or get electric power and a dehumidifier or move to a drier climate.

Check out the Eva-dry renewable dehumidifier. This is a renewable item which will dehumidify and then you can restore it to work again. It does not use electricity to remove but uses a little to renew. There are different sizes for large and small spaces.

+1 on this product. Works better than a typical dehumidifier.

Let's assume the OP had electricity for say 6 hrs/day. running a compressor driven dehumidifier for that length of time will likely solve the condensation problem. It may take a few days but should help a great deal. Mine will often pull 2.5 gallons out of the air in 6-8 hours. Once it gets the humidity down to the 50% range or so, it pulls out about 2-3 gallons/day.

Long term use in other than a very dry climate IMHO pretty much means measures to prevent moisture buildup. In moderate humidity climates, opening windows, fans on etc. when cooking, showering may be enough. But when humidity rises outside and/or it gets cold at night, that is often not enough and a compressor driven dehumidifier is appropriate.

IMHO the peltier devices or damp rid type are fine for storage, but can't pull near enough moisture out when trailer is in use.
