Dehumidifier recommendation wanted

As you know today has been rainy all day and I've been stuck in the trailer while DW is in Tallahassee visiting DD for a few days. This one has kicked to low and keeping it in the 40%+/- range. Amount of water varies with the weather; yesterday was hot and dry and there was only a bit of water in it last evening. This morning it was full after this front came in.....

Until you get used to it you might just pick it up and check under it after it's been running to make sure it's not getting the floor hot. I had mine on a thick, rubber backed entry rug type of thing I cut out to fit.

Yes, the camper is all closed up. I set it on automatic and with that setting you don't choose a moisture setting. I believe it stays at 50% max or lower.
Continuous/manual run mode (which I am not using) is where you choose the moisture setting. I've seen it at 48% and lower when I go in there to check it. I'll feel under it next time to see if it is warm. Since it's not on continuous run mode, I don't expect it to be hot. Thanks.

Great topic and valuable, but I have some to add to it.


First I did order this one from Amazon, Thanks to those that recommended it as that is what it took for the wife to relent on this large of a dehumidifier.

My point is we go to the coast in WA and OR and will be going to ID and MT at almost any time of year. Get a larger CFM (essentially) to reduce the humidity faster when we are USING the RV.



We have no condensation problem when we are not using it, therefore, when we are parked/stored at home, we are using a Damp-Rid thing that has a fan and circulates the air. Since cold air won't hold as much moisture and the RV is not heated when not in use my hope is that this will be adequate. But for use with us in the RV and the temp differences and high humidity, we need quite a bit more dehumidification than damp-rid can do.


That is the plan anyhow, if it doesn't work I will advise.

I've found the best dehumidifier for mild/rainy weather is the one that comes on top of the camper. I take an electric space heater with me and force the air conditioner to run. We have a smaller camper with no slides, so maybe this isn't a great option for larger rigs.

The only problem with that besides wear and tear is the ac is probably operating below (outside) design temperature causing it to slug more liquid in the compressor..much better to just spend the little bit of money on a proper dehumidifier

I bought the camper to use. 60F and raining, mine will be fine.

Ok …sounds like you got it all figured out

Your probably right …you can just open the refrigerator or freezer door if it gets too warm from running the heater so you can run the air conditioner so you don’t have to use a dehumidifier

Seriously though I could care less I was just offering an opinion and wanted to put that out there because it seemed like a Rube Goldberg way to dehumidify for anyone else reading and contemplating that “solution”

Having two high amp draw appliances running at the same time isn’t a great idea and space heaters plugged into cheap rv outlets is not a good idea either..

Whatever works for you…more power to you my friend

My boat HP unit does have a dehumidify option where it samples air then runs intermittently to dehumidify but it’s water cooled and will cycle on head pressure drops…it’s mainly for in-water boat storage in the summertime

I'm thinking about getting this dehumidifier:

Thoughts?

[JBM3M]

I would go for the climates you are in.



I need overkill because my travel is in the PNW. The one I got works marvelously, almost a quart of water overnight with cold temps, snow, rain outside. Windows did not fog up last night, the first trial.

I wouldn't waste the money. Don't know what a "thermo electric" dehumidifier is but the absorption has to come from something and I figure it's dessicant or something like it - useless IMO for an RV application.

Looking at it another way it says it will collect "up to" 20 oz. of water per day = 1 1/4 pts. - useless. My prior dehumidifier (in the barn now due to size) was a 35 PINT per day unit - excellent. Current one is 11 PINTS per day and does a good job. Both are compressor driven and the only kind worth spending money on IMO. I've owned one like you linked...threw it in the dumpster after 3 days.

Ivation has a good, small compressor driven dehumidifier that actually works and pulls lots of water out of the air;

I would have linked to the one I'm looking at in my RV but you can't get them any longer it appears. Note the one I linked says something about "up to 320 sq. ft." or about the size on the inside of an RV, the one you linked to just won't do anything.

Give 'em a hand full of salt when you get there.

Hi Danny, This looks good. thanks!

Danny, per your recommendation I bought the Ivation dehumidifier and it's perfect.
