Hi Everyone.

I have an R-Pod 178. 

I've been having an issue with mold building up under the mattress and on the warm side of the plywood bed frame in my R-Pod. This even happens when the weather is warm and dry outside. 

I'm assuming this is simply condensation build up from my body heat keeping the mattress side warm, and the cooler air being under the plywood bed frame (half the frame is over the rear unheated storage area of the R-Pod).

Has anyone had a similar problem, and how did you fix it?

I'm thinking about putting a Styrofoam sheet down under the mattress to help insulate the mattress inside from the cooler temps from the storage area. 

Any ideas?

Thanks in advance

I know you can get a lot of condensation build up inside a pod just from the moisture in your breath. It is always good to crack a window and leave the bathroom fan on low to get some fresh air flow in the camper. When the camper is  left for a while I put Damprid in it to keep the moisture down. Damprid is just a calcium cloride moisture obsorber.

Last summer I put a layer of that foily bubble wrap insulation under our mattress to add some insulation from the cold air in the pass through below the bed.  At the end of the weekend I discovered soaked sheets and the underside of the mattress.  I predict styrofoam will produce the same result.  We live in a very dry climate, but I guess respiration adds a lot of moisture.

I insulated the storage compartment with Styrofoam walls and ceiling, I have no problem.

When you insulated the storage compartment, did the styrafoam have the foil side to it? If so, which way did you point the foil?

So I guess essentially you made a "cooler" out of the storage compartment?

Thanks for your reply

No foil just 1 1/2" Styrofoam.

I was thinking of adding one of those covers over the wetbath fan and leaving the fan door open 24/7 to prevent mold and condinsation, is this a good idea or will rain coupled with winds still get into the wetbath.
 
Other than that i might have to try some of yalls other tricks to avoid this problem i am highly alergic to mold and do not want to deal with it. For now while not using my trailer for week or two at a time i am just moving the mattress to where it sits half on the wall and base so that its not just flat on the base and have the wetbath fan door cracked like an inch or so. Im checking it every other day to see if i have any leakage or mold issues.

I think the mold was caused by the cooler air from the rear storage compartment, meeting up with a warm mattress (my body heat). I've never noticed mold anywhere else, just that spot.

Condensation in an rpod is a tough battle. When it rains and you're hanging out/sleeping inside, humidity will win. Just be prepared to wipe things down in the morning. Air flow is the key to preventing mold.

I cut a hole and put an air vent under the bed to help create airflow from the rear storage compartment and the inside of the rpod. Not sure if this will work. I'm heading out for 6 weeks so I'll definitely find out

I always left a window cracked open and my vent open a crack when in storage.  I didn't have a cover over the vent but didn't care since it is a wet bath.  Little rain got in and whatever did either evaporated or went down the drain.  Some people leave their fan on low all the time if they have power where they store theirs, I didn't.  I never had a problem with mold even though we are in a very humid area.

I considered cutting a hole under the bathroom in the pod, and a rear-facing vent underneath.  That would have allowed for air flow through the grate just below the bathroom door w/o leaving the windows open when it rained.  Never did it.

I did install a fan with a cover on my current camper since it is a dry bath.  I plan on leaving it wide open all the time.
