We have been using a Pro Breeze 150 SF (1200 CF) dehumidifier in our Ollie plugged into shore power while in storage here at our home. We emptied this dehumidifier every 5 days.  It just was not enough machine to get the RH down to a target range of below 50%. This smaller unit has struggled to bring the RH down to 68%. So we ordered the next size larger 250 SF (2200 CF) and are going to give it a try. Hopefully this new unit will drop the RH to less than 50%. 

We monitor internal temp and RH humidity remotely from our home with a remote weather station - channel 1 & 2. Channels 3 under curbside bed and 4 is located in the battery compartment. Is anyone else using a dehumidifier while their Ollie is stored? 
Care to share what your using?

I purchased the Pro Breeze 2200 for ours, but it would not get the humidity down below 60%.  So last week I went to the local big box and picked up a 20 pint GE dehumidifier. The GE is a bit large to carry along on trips, but I am happy to report for storage it is working great.  I have it set to keep humidity  down  to 45%. It dropped the trailer to that in less than an hour.  I have had a slightly larger GE in my workshop for about 4-5 years and it has worked continuously without problem, so that is the reason I tried another GE.  I don't know how Western NC compares in humidity levels with Raleigh area. Hopefully, it is not as bad, but I am guessing it is probably the same. We will use the Pro Breeze when traveling.

Question: how long has there been an outlet there? Or did you add?

Here in Maine, in the Winter, our RH is quite low. Our question is how often do you have to empty the container? Would the contents have a chance to freeze? Is there a way to drain into a different container. Thinking a bucket filled with nontoxic antifreeze?

All the 2020's have an outlet there.  I am not sure when it was added. The GE has a bucket and also the option to add a hose to have it drain. I am emptying mine every other day or so.  I may shut it off when it gets colder. It becomes less effective below 41, but then the humidity usually drops when it gets that cold here.  We are expecting our first freeze here next week. I think they are show 29 on Tuesday morning.

Like the outlet there. Should be easy to add. Will have to look at another "maybe add" in early Spring. Would be easier to plug in while sitting at the dinette than somewhere between your legs where the outlet is hidden by the table. On second thought maybe we better look at the overhead. Maybe between the cabinets? So no cord to trip over?

That outlet came with our 2020 Ollie. We on occasion have a chance of freezing temps here and I plan to run the furnace on those few nights in the short winters we have here. Or just pull the dehumidifier as to not damage it. 
So we’ll see how it goes.

Ray, 

Thank you for this great feedback. We will be keeping the 2200 Pro Breeze for traveling as well.
Would you mind sharing more info on the GE unit you purchased. Lowe’s or HD? 
Thank you,

David

It was the HD.  Here is a link: https://www.homedepot.com/p/GE-20-Pint-Dehumidifier-ADEL20LY/310574305

The price was 159.00

We just ordered and received this dehumidifier. Haven't had a chance to test it out, as our Oliver has not been delivered yet (but soon - very soon!).  I might try it in my potting shed at home and see how it performs.

While researching humidity control, I did not know there are different types of dehumidifiers: some designed for controlling humidity while the trailer is in storage and others (more efficient?) for use while the trailer is occupied - the reason being that there is more excess humidity created when live bodies are involved.  Thus, square footage is not the only consideration.  Since we are more concerned about condensation at night, when the temperature drops, the trailer is receiving less ventilation, and we are sleeping in a more enclosed environment, we opted for the "dessicant" type.  Maybe someone can explain the differences in the types.

I will report the findings on my potting shed test.  The square footage is similar to the Elite II and it is insulated, though not as well as the Oliver.

Ray,

Thank you.

We will be installing it this morning and giving it a try. I would like to drop the RH to less than 50%. 
 

**Edit with a few photos - just installed the GE unit, it’s hefty in weight - box says 33#. Instructions say to set the unit to lower H to 45-50% during first 24 hrs of operation, done. My only concern will be to ensure it does not dry out our sink, shower traps and toilet from antifreeze too quickly. We’ll monitor this for a week and see how it does. A pic showing the size comparison to the Pro Breeze. This Tuesday & Wednesday we may dip down to a freeze point, so I will need to keep an eye on the dehumidifier so that it does not freeze up. A work in progress.

Would it help to plug in the drains while dehumidifying to prevent this?  Another thought: would removal of water from the P-traps by dehumidification increase the concentration of the antifreeze?

We’ll keep the smiling little guy for travel 😄. Although I think it’s not going to be very effective when we are in and out of the Ollie. It maintains about 69% RH. Better than nothing I suppose. 🥴

It would be super easy to seal off those traps to block the room air, so they don’t dry out and get smelly. For the floor and each sink, small circles of sheet rubber or pieces cut from an old mouse pad. For the flush toilet you would need to wrap the bowl with plastic kitchen wrap. 

In our semi-arid climate I have no need for a dehumidifier, the relative humidity stays below 50% and fairly constant in my Ollie, stored inside an attached, insulated (but unheated) RV bay. Plus the temperature is very stable, which reduces the possibility of condensation from large swings....The house OTH requires a whole house humidifier for the furnace, or the RH will drop to 20% or less. Snap crackle pop! Blue lightning from your fingers! With the humidifier it stays at more comfortable 45-50%.

Yes to your first question, the toilet will still need a cup or two periodically. Second question, we’ll see. I have the new unit set to reduce the H to 50% for now. A work in progress.

Great suggestions John, I have not wrapped a toilet seat in Saran Wrap since pulling a trick on a few friends many many years ago.😂 I will spare the details. Well I did get tossed into a pool full clothes as payback. 😂 Those teenage years were fun. A beverage and campfire story for sure.

Thanks for the suggestions!

We have a compressor type, whole house dehumidifier in our home in Florida.  I've not used a dehumidifier in the Oliver, yet.

I was curious,  too, about the difference between compressor vs dessicant dehumidifiers.  Thus article was pretty informative. 

Dessicant type is more quiet (I'd like that, in the trailer), and more efficient in cool weather, below 15c/ 59 f, or so it says.

Very interesting link, Thank you! 
I just read in the owners manual not to run our new GE dehumidifier below 41 degrees or above 90 degrees😳. So with temps dipping below freezing I will just empty it and turn it off this mid week at night. The GE model has a high and low speed and it’s pretty quiet on low. A continued work in progress. 
 

Here is the GE we purchased recommended by Ray.  We bought at HD - it’s heavier than it looks at 33 lbs empty.

Yes, those compressors are heavy.

JD - I too would like to see the person that threw Patriot in the pool.  I've had the pleasure of meeting Patriot and his lovely wife and he is not a small guy by ANY means.  And, he's in pretty good shape too.

I don't know if there was a Halloween orange edition, but the snowflake/holiday cling wrap should be enough to alert anyone that the toilet is "winterized. "

Just a follow up with the GE dehumidifier listed above. We learned in the owners manual that it should not be used below 41 degrees or above 90 degrees and its heavy as a boat anchor. So we returned the unit to HD yesterday. So our search continues. We will keep the Pro Breeze for travel.
