Humidity

I read this can become a serious issue for RV's. What to do to control it? I heard about those moisture sucking bags to battle any mould starting...do they work? Is there a small R.V plug in de-humidifier? The AC would work I guess? What do you guys/gals do?

Constant humidity (excessive moisture) inside the RV can be detrimental to all sorts of things. I've seen many examples of various ways to combat it and I'm sure folks will chime in on what they do.

We live in a dry part of the country so for us we have no need for dehumidifying. When we travel to humid areas (coast) we have a HiSense dehumidifier that we take with us. It is a 35 pint unit and does an excellent job of keeping the humidity down.

The AC will keep it down as well depending on what you setup is. We have a main 15k AC that will extract the moisture. Our 13.5k in the bedroom runs continuously and makes the bedroom feel "clammy" if we don't run the dehumidifier.

Curious why your bedroom is "clammy". Do you keep the door closed to the bedroom all the time? If the compressor is running then it should pull out the humidity. If the door is closed and the compressor is off because the thermostat is satisfied then it will not reduce humidity as you are just running a fan.

This is what I use, an Eva-Dry electric de-humidifier. Peltier Technology, low power consumption, quiet and no added heat.

I put mine, which I purchased 5 years ago, in my camper as soon as the nights stay above freezing and it runs 24/7 while at home and whenever we're using campsite shore power and it stays on until I winterize. It doesn't pull out as much water as a compressor based unit but it works well enough. If I get to the point where I need to remove more water I'd get another rather than using a compressor based unit.
'

When I first got it I had a 19' Hybrid and it would get clammy because of tent ends, this little unit worked so well that we would go to bed at night to totally dry sheets.

Based on my experience I recommend it.

Thanks for the replies. Sounds like those moisture sucking bags don't work that well...I heard there sold at Home Depot and the like...I was hoping they would do the job instead of having a de-humidifier running constantly. I may try them in a decorative bowl of course and see how it feels :-)

What are you trying to accomplish? What part of the country? For months at a time?

Let me say a couple of things, if you are living in the unit, keep a window cracked 24/7 in the heating season. We use a small bedroom window for ventilation. Use the exhaust fan when bathing. In the cooling season the A/C will keep the humidity at bay. We winter in a 700+ spot resort in central Florida. For those that leave there RV on site during the summer they place a dehumidifier in the shower with a open drain (one with automatic controls) and maybe set the A/c to 85deg or so. There are also full timers that will check on your unit for a nominal fee.

Other than that, it all depends on the many variables, so no one answer will fit. If you are trying to winter in one in the frozen north I have no idea.

Ours doesnít run constantly once it gets to the selected level it shuts off, until
It rises again!

Been using these for going on 4-years. They work great. We have them out of sight, everywhere throughout the 5vr. Oh, we pick them up at Dollar Tree... so now you know how much they cost! Or you can pick them up elsewhere for $5.00 each!

Our summers up here in Ontario can get very hot and humid. Unfortunately my RV will be in outdoor storage for most of the camping season...still doing the old 9 to 5 thing. We will be camping for only 32 days out of the spring, summer, and fall. I like Alpine's idea especially when stored in humid weather. I'll picked some of those up and a humidistat to see how it works while camping. A battery operated fan would be a good idea while in storage and no access to power. A dehumidifier takes up space and it's another thing to plug in. For our amount of camping I think the moisture absorbers are the way to go.

Thanks all

Hello again, another RV related question those awning tie downs, are they recommended/okay to use? Probably not good to overtighten them.

Robert, a very good question and one which should probably be answered in its own thread. Start one with that question and I'll bet there are a number of opinions.

It is possible you could use those tie downs to help prevent your electric awning from flipping over but in my experience, those tie down only work with a manual awning and not the electric ones. I used to use them with my manual awning and they worked well, they do not work at all with my electric one.
