Bikemike Posted December 4, 2016 Share Posted December 4, 2016 Since the weather has turned colder we have noticed A Lot of moisture accumulating on the underside of our 5 in. open-cell foam in the morning. My wife, child and I have been parked out in front of my sister-in-law's house in Salt Lake City for a few weeks while visiting family. We plug in w/ an electric heater pointed up towards the cab over bed and stay comfortably warm under the covers. Last summer I cut out pieces of 1" insulation and "accordion" or "lattice" -taped them together so that the foam could be easily folded up for installation/removal. This also served the purpose of leveling, due to the fact that there is a 1" thick (foam/wood sandwich board thing) covering the hole to the cab area and protruding into the sleepers back. So. Now we have (I think) two layers of insulation plus a five inch foam and a little bit of metal separating us from the freezing temperatures below us. I don't understand why we would still be getting condensation forming between our mattress and the shiny silver 1" insulation board. I realize that our bodies give off moisture and that the 1" insulation will be a cooler temp...but I wonder what else we can do?? Each morning I prop up the mattress to allow for evaporation and remove the mattress occasionally to thoroughly dry it out in the sun. I wonder if this is standard fair for RV sleeping in cold weather? Or a peculiarity of my set up? Quote Link to comment Share on other sites More sharing options...
WME Posted December 4, 2016 Share Posted December 4, 2016 Yep to happens to most cold weather campers. Here's is what the boat guys do about. https://www.miamicorp.com/products/MARINE/HYPERVENT.aspx Quote Link to comment Share on other sites More sharing options...
Bikemike Posted December 4, 2016 Author Share Posted December 4, 2016 Thanks, that's helpful. I wonder what a cheaper substitute would be? It looks like the material that is used on floor polishers. It would be nice if I could repurpose some carpet or, even better, some Astro turf.... Quote Link to comment Share on other sites More sharing options...
DanAatTheCape Posted December 5, 2016 Share Posted December 5, 2016 humidity control is an issue in toys, Winter camping is a problem. You have to "air it out" on a regular basis. a couple of humans will make a lot of moisture - then do some cooking, take a shower, wash dishes....

Bikemike Posted December 8, 2016 Author Share Posted December 8, 2016 ...ok, I wonder about this for a workable solution. Home Depot sells a sheet of plastic lattice that I can elevate up on some slats/blocks. I can level our bed and get a layer of air under us at the same time.

The plastic lattice that the local home depot sells is flimsy, not sure it would work? There are 2 different grades of wood lattice, I would think the heavier one would work. Simply the opinion of a lifetime tinker and putterer not to be confused with knowledge or wisdom. Quote Link to comment Share on other sites More sharing options...
linda s Posted December 8, 2016 Share Posted December 8, 2016 Karin posted a product just for this purpose and I can't find it. Been searching but got nada. She was pretty familiar with boats too and this I think was a marine type product. I'm afraid it might be lost in that monster thread "what did you do to your toyhome today".

Totem Posted December 8, 2016 Share Posted December 8, 2016 I too remember the product Corbin K. found. It was like plastic mesh stuff to put under mattresses for marine bedding environments; designed to create some air underneath the cushions.

Bikemike Posted December 9, 2016 Author Share Posted December 9, 2016 Ok, I did it! The mattress was dry in the a.m. When I put my hand between the wall and the bed and rolled around, I could feel a movement of air. I cut up a bunch of blocks of wood for "stilts" instead of framing to increase airflow. I know I could've bought some Hypervent but this was more fun. We'll see how it holds up. The lattice was half price and the wood 70% off at Home Depots (imperfects)-$25 Quote Link to comment Share on other sites More sharing options...
