Dehumidifier?

Hello guys,

We’re pretty big family, every morning all windows covered with moisture.

I saw on Amazon there are a lot of small dehumidifiers, something like that:
Dehumidifiers

Does anyone have good experience with these small dehumidifiers?

This specific model probably not big enough for 28 ft trailer…

don't waist your money on those small units. You need one that can remove 5+ GALLONS of water/day. Get a smaller compressor based unit at a big box store, you will find it will fill up in a few hours, empty it and then it may go 12 hours or even a day.

next what introduces water into the air
1) people breathing..... more water than you think
2) stove/oven. they will dump about 1 gallon of water into the air for every gallon of propane burned
3) damp clothes
4) NON VENTED heaters, (not a furnace) same as stove or oven. A vented heater (propane furnace) introduces ZERO, NADA, not one drop of moisture into the air, all the combustion air goes outside. Same with the water heater

So once you have a dehumidifier running, when you shower or cook crack a roof vent. try to keep wet stuff out of the trailer.

We often camp on rainy days in oregon, even with 5 of us in the trailer with the dehumidifier running and reasonable use of oven, stove, showers etc. we can keep the RH down enough that windows stay clear.

The dehumidifier that you linked is only rated for 18 ounces per day. You'll need something more along the lines of 25 pints per day and that may only put a dent in it with a large family. An individual adult can exhale three pints of water while they sleep, part of the reason why you are thirsty when you wake up. Then there's showering and cooking which releases moisture into the air. I lived alone in my 28ft travel trailer for a while, using a 25 pint per day unit that I had to run continuously throughout winter. I showered once a day while running the ceiling vent and only used the microwave. The dehumidifier was barely adequate.

turn on some electric heat and open a roof vent.
