Just got back from a trip into the blue mountians in our camper trailer which is made out of folded checker plate and gal steel (yes its heavy and well bulit)

The floor where the fomies lie, sits directly in contact with the metal.

After a night in the cold and us lying on top of them, the bottoms of the fomies are not dripping wet but coniderably damp. We went away two weekends ago and I guess the same thing happend but I did not notice it as there was mildew build up on one of the foamies.

No.....the kids or us did not wet the bed !!!

I'm looking for solutions to try and stop this. One thought I had whilst driving home was to get som 6mm Ply to sit between the metal and fomies?

Any other suggestions? What are the floors in most camper trailers made out of as its not something I've thought to much about till now?

By fomies I assume you mean some sort of mattress.
Have had a similar problem with foam mattresses when we first made ours, cloth both sides.
Had condensation gather on the underside. Replacede the cloth with vinyl and all is OK.

the condesation is formed the same way it does on a cold stubby, thus stubby holders!! You need to add an insulation barrier. This can be as you thought by some ply or if possible make a "futon" floor like lattice. If both sides of the camper floor is the same temperature there will be no condensation.

Hope this helps.

Some sheets of ply will do the job.

Don't agree David.
We had the same prob and our floor was 5/8 inch ply. Tried an overlay of closed cell foam. The type they use in sleeping mats. Still did not work. Have since installed a "Campercoil" innerspring matress. Problem solved.

Hi Guys,

Agree with Vince on that one. This seems to be a common problem. I have just purchased and innerspring mattress at the Brisbane caravan and camping show and it is ventillated to help stop the moisture and we believe it will fix the problem. Our camper mattress sits on 16mm ply as well and the ply does not appear to stop moisture buildup.

cold surfaces on one side while warm on the other will attract moisture

Hi Paul,

Must be the camping destinations - aim for warmer climes (Nudie that would be hot on hot and no condensation). I have never experienced this condensation thing and yet I've read so much about it. Presume we are just not camping in climates cold enough to make this happen.

Kind regards
