Full-Timing in Humid Conditions

Hello everyone!

We're lucky enough to be able to spend the fall/winter months in beautiful Tofino, British Columbia. The climate is great for a Canadian winter which sees little to no snow and temperatures that rarely if ever get below freezing.

The issue we do have though is that it's very humid here as it rains A LOT. In fact, we're camping in a temperate rainforest. As beautiful as it is, we've been trying to combat condensation in our 5er. The main issue is small amounts of condensation droplets are accumulating in spots that getslittle to no air such as in closets, behind the couch, etc...

Here's what we've done:
-we run a small dehumidifier that worked perfectly in our previous setting
-we run a space heater and alternate it in various rooms of the rv
-we constantly run the ceiling fan to circulate air
-we have a Eva Dry rechargable dehumidifer that we place in tighter spots
-we've wrapped some but not all windows
-we've kept some cupboards open to promote airflow

These solutions have helped some but aren't completely solving the issue. I honestly don't know if the issue can be completely solved, but I'm wondering what steps I should take next.

I was thinking that I might skirt around the RV similar to this: http://www.crystalcove.ca/sites/default/files/styles/flexslider_front/public/tofino-glamping.jpg?itok=T5Z8Kb_N

...and on the inside of the skirting, insulate it with foam board. I'm unsure of the cost however and although it will keep us warmer I wonder if it will help with condensation at all.

The other thing I was considering was buying either another space heater or a larger more powerful dehumidifier. I'm leaning towards the extra space heater as it will serve a dual purpose once the temperature starts to drop more and hopefully it will also dry out some of the condensation.

Looking for any tips, advice from those that have lived in similar instances before.

Thanks in advance!
  • Hi,

    Because the air conditioner with a space heater running draws moisture from the air. It is far more effective than a stand alone dehumidifier.

  • The air conditioner removed moisture from the air inside and it then runs to the outside. We have had situations where it really wasn't warm enough for the A/C but was very humid inside. We have run an electric space heater at the same time as the A/C to keep it from getting too cold inside. After 1/2 hr or so the humidity will have dropped 10-15%. Only other thing I can think of is to get a bigger dehumidifier like you would use in a house that can pull more moisture out of the air than the small ones can.

  • If you have sufficient power, run the electric space heater and the roof air conditioner.

    If those space heaters are unvented propane heaters, they will actually make the problem worse as they make water burning propane. By far the two best "bang for your buck" measures are that dehumidifier and skirting/extra insulation. If the "cold wall/floor" is in the right configuration, you might be able to benefit from a sheet of 2 inch thick styrofoam taped or propped next to the outside wall/floor. Styrofoam in 4 foot by 8 foot panels are fairly cheap from building supply places.


    The space heater is electric as we've been trying to avoid the propane for heating based on the issue you state.

    The insulation I was thinking about getting was this and just cutting it to size to fit the areas with condensation. https://www.homedepot.ca/en/home/p.eps-rigid-insulation-96inch-x-48inch-x-1inch.1000116769.html

  • The dehumidifier would do you more good than the space heater. You can be warm and pretty humid at the same time. As a matter of fact, warm air will hold more water vapor than cooler air.

    My guess is that most of your problem areas are on outside walls, and they are cooler than the inside. The space heater won't do much for the wall temperatures.
