Getting really humid in sleeper?

Plugged up cabin filters causing poor air flow across the evaporator will cause high humidity levels. Also clean your AC drains, they maybe holding water. When the AC is working properly you shouldn't need a dehumidifier.

 

Your theory on not running the AC certainly makes sense, since air conditioning does remove moisture/humidity from the air. Humidity is good for our skin though, isn't it? As long as the air temp isn't too warm (or cold), making the conditions uncomfortable.

 

Sleep with your windows down.

 

don't go to floriduh !!

 

High humidity for lengthy periods, especially in cooler/cold temps in a confined space is an invitation to colds and sore throats and other miserable illness. (Ask any recruit who's attended Great Lakes Naval Training Center in the winter) A truck in and of itself can not "produce humidity", it is a result of the interior humidity being balanced to higher humidity outside (open windows/vent) or human breathing in a confined environment over a long period with no climate control (a/c). The only thing that will "dehumidy" is a/c and/or defroster (with condenser activated). Not sure what you bought but don't be surprised if it turns out to be waste of money.

 

If you don't keep up on basic AC maintenance your AC system can become a moisture generator by transferring moisture through the ducts into the cabin. Eventually you'll end up with mildew odor from the ducts if the drains are not open and working properly or your filters aren't allowing airflow. High moisture in the cabin allows micro organisms to breed rapidly.

 

Go to Wal-Mart and over by the ironing supplies you can buy either a bag or bottle of a material that you just place in your sleeper that will help absorb the moisture in the cab. They are like gel so they will need to be replaced once in awhile.

 

I agree that your AC is the key here. Coupled with the naturally more humid weather conditions across the country this year. But check that air filter out, and if it is good, then have the AC checked by a pro.

Oh, one thing more. You are supposed to pee IN the bottle, not on it. . .

 

Yup, that's the safe thing to do.

That way you won't have a bunch of broken glass to walk through when someone comes in your truck.
Quieter as well, so you won't even be woken up by the shattering glass.

Sleep tight.
