Dehumidifier for TC

Like others have said, you need some ventilation. We use the window to the truck cracked open and the bathroom vent (has a Maxair cover) cracked open.

Oh, I almost forgot. Quit breathing. That's probably 90% of your problem for sure.

We 'snow' camp all winter long...I think 10-11 trips this season so far.

With that, the answer is, as has been stated, air flow. Doesn't really matter much where/how...but it has to have flow. We usually leave the kitchen window cracked and the bathroom vent opened up. A dehumidifier would just be another piece of junk stuffed in the camper to walk around and would need power all the time.

I'm a fan of the KISS doctrine..

A furnace does not add humidity to your camper as the exhaust is vented, and if it does then you have a bigger problem then the humidity.

You should get in the habit of changing the air especially when cooking. Open some windows and a vent when cooking (especially boiling water). Then shut the window till bed time and reopen, leave a vent open slightly all the time.

Also if you are showering or drying wet clothes you will create more moisture then you will be able to vent this time of the year.

I opened a vent but not a window, im going to try to crack up a window by my dinette next weekend.

Yep, that is about the same as not opening anything. The lower the window the better. Or you could even open one of the truck bed access doors if you have them.

A small dehumidifier wouldn't be able to keep up with the humidity created by the lack of insulation, propane appliances, and occupants. A large dehumidifier would take up too much room and drain the batteries quickly.

I did check under my mattress and it was allright.

Its my 1st RV and im still in a learning process.

Thanks for the tips guys, i appreciate.

I also just double checked with the DW this weekend since she's the one who changes our sheets most times. We've had zero moisture under our mattress, ever. Do you guys with moisture under your mattresses have mattress pads on your mattresses? I'll note we also have reflectix under our mattress.

There was a dehumidifier made for boat and RV use, no longer made. But you find them every so often on eBay. Search for "dh5 dehumidifier -hisense" on eBay, within a month or two one will likely come up. These are a small countertop real dehumidifier (not the cheap peltier devices you find now). It is arranged so that it will drain directly into the sink. They were made by Arrow, you will find them also in a SS cabinet (that was the marine version).

I wish that the RV suppliers would make a rooftop dehumidifier/vent to replace the AC unit. In a lot of climates, that would work very well and be capable of battery operation. 90 degree weather isn't very bad at all, if the humidity is <30%.

We always vent thru windows and or top hatch. We had moisture even under mattress prior to learning the venting thing. Do check under mattress if you have not done so.

Definitely check under your mattress for dampness (and mold). We ended up buying a product called hyper-vent and putting it under the mattress to be on the safe side. It is a type of plastic mesh that allows air to pass through it and eliminates hot mattress resting on cold roof platform over truck cab and creating condensation that is absorbed by the mattress.. Well worth the money in our opinion.
