right dehumidifier

I assume that you can run the dehumidifier setting on a counter and draining in the the sink? then periodically you would have to go out and dump your grey tank? but yes I agree get a real standard dehumidifier.

I agree on an additional small fan to circulate air.

I set mine to 45 percent humidity. So, whole coach probably averages just over 50 percent humidity.

And, likewise find it removes a lot (fills reservoir in 2 days)when coach first put in storage, but quickly tapers off to where the reservoir only needs to be emptied weekly.

I've got one that holds about a gallon and a half that I use for my FW here in Florida. I have to dump it twice a week in the summer and I found that I also need to use a fan to circulate the air in order for it to work correctly. I had it setup in the kitchen area and last fall I found that the pillows in the bedroom mildewed.

I keep the bathroom door partially opened and run a household fan on a timer. I keep the dehumidifier set on "medium" and dump it twice a week. It seems to control the mildew and smells in the RV.

About once a month I dump a little of the water from the dehumidifier down each of the drains in the RV to help keep smells from the holding tanks from coming up the drains.

go with the smallest REAL dehumidifer you can find at a big box store, around $100 typically. Usually holds 3-4 gallons, don't ask me how many pints that is.

We've used on for years, when first turned on it will pull two buckets full out in 24 hours, roughly 5-6 gallons of water. they run a compressor, basically a a/c unit, water condenses on the cooling coil. they will also give some heat to the trailer.

unless your in a real dry climate, stay away from the thermoelectric units, they can't pull anywhere near the water out that you need.

I am going to get one for the 32' fifth wheel. I am concerned about keeping the humidity down when it is in storage.

I have one of the basement models for the big job in the stick home but think there is a solution for a much more portable one just for the fifth wheel.

I even read some on the Thermo Electric technology ones.

Sometimes it is pretty chilly out there in the barn so if I do not have to use heat to keep it warm while dehumidifying, that would be nice.

I may even take it with me in the winter to aid in taking moisture out when it is cold outside and the windows get wet inside.

Point me in the right direction please.

Check out a chemical dehumidifier. Doesn't use any electricity, should work well as long as you're not in and out of the trailer the entire time it's in storage.

edit: I just re-read your post. You mention storage, but also mention "take it with me in the winter"

What does storage mean to you? Is storage being parked for a week or two between trips, or does storage mean lock the door, see you again in 4 months?

I'll have to be contrary with the previous posters who claim a small dehumidifier works for them.

I started with a 20 pint, and found it totally useless in the RV for winter camping. When I go camping in the winter, it's in deep snow - snow everywhere! The dog and I will be out in a hike, we'll come back both covered in snow. The 20 pint did nothing with that water load, despite how small my trailer is. The windows were dripping, the walls were dripping, it was not good. I stopped winter camping at that point (my first year), and bought a bunch of chemical dehumidifiers to dry out the camper, until I opened it up again in May.

The next season, I bought a Whirlpool 90 pint dehumidifier. It is actually smaller and quieter than the 20 pint, and the wattage is the same.

In the summer, it pulls 2 gallons a day from inside the camper, that's with the rooftop AC running. I guess the dog and I perspire a lot.

In the winter, it keeps the walls and windows dry, it makes the air comfortable. The heat it gives off is nice too, the furnace runs a bit less.

A small (30 pint) house-type dehumidifier works very well.

Have used them on all our sailboats and motorhomes.

If convenient to where you live, just plug it in. If not, use the exterior drain hose option and drain into the sink or shower/gray tank.

I bought a small one for the RV. It works just fine.

The larger ones are a REAL big drain on electricity and create a LOT heat from the unit. You really don't need a honkin big one for the RV.

When I went to buy one from Lowes one entire shelf was empty where the smaller ones would have been.

I talked to the manager and he said it was Snowbird RV season when they all head back leaving RV's and/or Winter homes behind needing de-humidifier's, and every year the small midsize dehumidifiers all sell out in one full sweep! So there's your recommendation from the Snowbird crowd! :C
