The Most Dangerous RV Enemy -- How to Eliminate RV Moisture

[@rainbowpcdash]

I just now put a little dehumidifier in my camper to help it

[@sgtbrown4273]

Thank you for your review. I work in the compressor world, so cheap, desiccant i have I have a fan and small cute bucket full of rechargeable activated aluminum. It's not practical for most, but i can get my geo pro down to 8% RH, so dry it makes your throat feel weird 😂 i may need to tweek it a bit.

A point of clarification. Hot air mixing with cold air does not create humidity. There has to be moisture available to be absorbed by the air for the humidity to rise. Warm air can hold more moisture than cold air. That's why the weather people always say "relative humidity". Alaska is the state in the union with the highest relative humidity, although there is less actual moisture in the air in Alaska than in southern/warm states. Hot and cold air mixing can cause the humidity in the hot air to condense and fall out causing moisture to appear on surfaces, like when your RV windows get condensation on windows in the winter. If you have hot moist air, like from your shower, and it contacts cold air or surfaces you get water accumulating on surfaces, but it does make more water get into the air. Just because the two different air sources mix. The water has to come from somewhere. Everything else you said is spot on. Breathing, perspiration, damp clothes are sources of humidity increases, but let's not forget just opening your doors and normal air infiltration from outside. If you turn your fans on, the air leaving creates a vacuum and causes other air to be pulled in from outside. It's still an improvement, when you are doing this that cause humidity (shower, cooking, etc), but if you aren't doing anything that raises interior humidity it is probably your trips outside or air seeping in that could be raising your humidity. It makes me wonder if anyone makes a small dehumidifier like the one you showed that has a live drain instead of a reservoir that you can plumb into an existing drain line so you don't have to dump your tank twice a day.

[@EndlessRVing]

[@frankenstein3163]

Will damp raid and/or ventilation help as I have 90% humidity for 3-5 days at time with 8% give or take per a day. Only like 1-3 days that are less than 80% before it starts all over again for more than 3 month a year. This is my out door humidity. have not tested inside. Or should I just get a dehumidifier ?

[@EndlessRVing]

A good dehumidifier is the best choice

[@wonderlust1035]

Good and honest info, thanks folks for your guiding me to this vid. Most of us don't stop 'n think ...when we shower, cook, sweat, breath (like in cold air we breath out vapor whether in winter or summer) like you say here, or use a air dryer ...wet dog ...ALL that moisture goes someplace, it usually goes the walls in the foam of mold & mildew. Next time someone goes to an RV salvage yard, take photos of wrecked RVs and the black mold on the walls of those wrecked RVs ...and consumers will fill their britches. It's BAD !!! I'm 75, retired architect and I dearly wanta build an RV the right way... in so doing, there's a neat built-in dehumidifier make in UK 8" Dia which can be installed with exhaust wastewater pipe to the ground which can be wired to turn on when a certain percentage of humidity is inside a van or RV. Why for the love of God is the RV industry NOT putting these in all units????? Keep up your neat Vids ....I just subscribed. Blessings

Gonna be living in a 5th wheel in Louisiana soon. Putting a roof over it though. I lived in an RV van for 8 years and mold nearly killed me. I`m very poor on a disability income so this was the only home I could find that I could afford. It looked very nice for 4500 so I immediately bought it. But I haven`t had it moved yet and haven`t done a proper inspection. Hopefully there are no serious issues but if there are I`ll have to pay to fix them. My sister will help me if it comes to that. Listening to the video as I type this. Looks like I`ll be doing a lot of outdoor cooking. I bought three 12 volt cookers and an Instapot clone. Just for the hell of it I plan to do a lot of cooking using the 12 volt cookers directly connected to a couple of solar panels. I went through some serious poverty and homelessness so I`m gonna try to be as self sufficient as possible with solar, food, and water just in case. I can run a small AC fridge and a freezer from solar if I need to and everything else below that wattage range. I tried to buy a cheap refurb power station from Bluetti for a small air conditioner and they screwed me over. Terrible company!

[@thecasualrver]

Great tips guys. One more tip. If you are using the LP furnance to reduce the moisture on the inside of the windows and in the interior, cracking a window or the ceilling vent can eliminate the moisture build up. It sounds counterintuitive but it works.

[@EndlessRVing]

Awesome tip John thanks for sharing. Izzy

[@johnkerechek6583]

Great points and tips. I’m lucky I have 20amp service where I store my rv so I run a dehumidifier. I’ll also run it when we are out and about camping; if we have electric hookup.

[@EndlessRVing]

We also are hooked up at home. We run the dehumidifier and it pulls a lot of moisture. Izzy

[@foxforpeace7351]

Preparing to do a van to RV conversion; have seen several van videos concerning mildew and mold of mattresses. Most recommend using a mattress underlay such as Den-Dry to prevent this problem. Especially a issue with full time van dwellers. Thanks for another very informative video!

[@KelleyTexas]

I use a dehumidifier when I'm using my trailer, and I keep fans running and use the A/C. I use the Eva-Dry renewable dehumidifiers (2 of them) when it is in storage. I check them every 1-2 weeks and recharge as necessary. This seems to work really well for me. I used to use the Damp Rid stuff, but it seems to leave a weird smell in the linens and such.

[@EndlessRVing]

I love those tips to help with the moisture in the Rv. That helps with getting mold and mildew. I didn’t know that happens to motorhomes. Thank you Izzy and MJ. I use a humidifier for my house and wipe down my shower after showering with a squeegee. Glad you can do that in a motorhome and or Rv. I love those tips. Thank you again Izzy and MJ.

[@slscamg]

Run the AC for everything it’s worth when it’s hot out. When it isn’t hot I just run one AC so it stays in longer to dehumidify the air.

[@EndlessRVing]

Yep that will do the job. Thanks for sharing. Izzy

[@kenanderson7321]

How do you keep the RV windshield from being fogged up on the inside when you get up in the morning?

[@EndlessRVing]

[@jerrygundrum1]

Depends on outside temps.....if it is below 40 probably not gonna happen. If it is in the 50s or higher run your roof vent on low over night

[@peggyshook6746]

We buy our dehumidifiers from dollar tree. They have one with charcoal

[@EndlessRVing]

Awesome!

[@GoatZilla]

When it's cold, I wonder if you could just run a piece of aluminum (like a rod or extrusion) from the outside to the interior, which will then just act as your dehumidifier. Circulate the internal air over it, and angle it down into a bucket.

[@EndlessRVing]

Maybe, but plugging in the dehumidifier works well and is easy for us. Thanks for watching! - MJ

[@GoatZilla]

@@EndlessRVing They also seem to consume a lot, lot, lot of energy... a dehumidifier is basically a heater and a cooler in one package. I think if you can draw the cold in from the outside (just like an uninsulated window), you achieve the same thing with just the power consumption of a small fan.

[@waynemitchell3882]

Hi there and thank-you for raising this issue. I wonder though how you deal with situations where the ambient conditions are at high relative humidities. Say for instance in sub-tropical regions. Do you keep the RV closed and rely on your AC to both cool and remove moisture from the space and then open the RV throughout the night and take advantage of cooling breezes or do you rely more on the dehumidifiers. I raise this as I am concerned with having to run the AC for extended periods of time particularly if you are having to run it off the generator. Wayne

[@EndlessRVing]

If we are out on the rig we run the AC. When parked not using we use a dehumidifier as we are always plugged in at home. Thanks for watching. Izzy

[@georgef.7434]

We leave the kitchen window open all the times. Just a crack will do it. (no matter what the weather) Use the vent over the stove when cooking, and run the fan in the bathroom, when showering. When home, parked in the driveway, we leave a small fan running, just to move the air around.

[@EndlessRVing]

Thanks for the suggestions. Izzy

[@mull3915]

Great video on a subject hardly never mentioned...we have terrible humidity down south in New Orleans. As a result, I run one of my ac's set at 85 degrees during the summer when on side the house between trips and a humidifier during the winter.

I live in south Florida and I keep the A/C running when it’s parked on the side of my house, plugged in to electric. Even with the A/C running and low humidity inside the trailer, my Damp Rod containers fill up in a month. I have one in the bathroom and one in the kitchen.

We are on the Alabama gulf coast and we keep our 5th wheel set up in a RV park near our home as a home base when we are not traveling. This means that it is always setup. We spent every weekend in it. So during warm humid weather both AC's are running at 71degrees so they keep the rig nice and dry. During cooler weather we run the furnace on 60 degrees as well as a large 50 pint 4500sqft dehumidifier. We have it setup in the bathroom with the hose dumping into the shower with the grey tank valve open so it continually drains. We leave our cabinets doors and drawers open when we are not there and have 3/4" venting material under our mattresses. So far we've had zero issues with moisture. Our Grand Design Reflection is pretty well insulated as least for this area.

I wonder how people deal with this problem when they live continuously in a damp area of the country, like the PNW? Especially in smaller rigs that may not have the battery power to use a “dry” heat source, like a ceramic or electric heater, and instead depend on a propane heater, which adds more moisture..?

A cheap idea for reducing the moisture in your RV when it is in storage. Put 3 or 4 pie tins with charcoal in them spread throughout the RV. Charcoal absorbs moisture. It worked great for us until a tree branch fell and put a hole in our roof.

Hi guys great video, I have used all those techniques and tips that you guys mentioned, and they work great. Right now we have two of the small dehumidifiers in the rear section and in the forward section. We do have those moisture monitors both in the living area and in the bathroom area and we maintain 40 to 50%. but I'm wondering about under the bed. It appear to have issues in the underside of my midsection bed area the storage area forward where you lay your head, there's another airspace there in the pull out that appears to be collecting condensation on the walls and dripping into the carpet. what we end up doing is pulling the mattress out lifting the led to area to dry it out. I have already checked all my outside seals the roof section on all the pull-outs used sealant over all the screws the seams and where your pull out May rub there could be wear marks there with holes and repair those and seal those up. That box section under the forward section of the mattress in the pull out where you lay your head is all closed in with a lid I drilled 1 in holes on the sides to ventilate under that area appears that's not good enough. Any ideas or or does anyone else have this issue this is a 40 ft fifth wheel with a midsection bedroom a forward bath and a rear living room kitchen.

Hi Guys: Catching up on your videos with my coffee this morning. Great video as always. I have always used damprid, open the cabinets, and left a couple of windows cracked (unless there is rain in the forcast) when the RV is sitting idle and have never had a problem with mold or mildew. However, the damprids fill up pretty quickly. I never thought of a dehumidifier for the RV, but love the idea. I am ordering one today. Thanks for the advice. Depending on the season and weather, we run the AC, heatpump, or furnace when sleeping. The AC and heatpump take care of any moisture issues, but I find leaving a window cracked when using only the furnace really reduces the moisture buildup on the windows in the morning.
