Dry air in cab?

I know sum drivers from down Monterey way.....says Your a fancy pants from up Norte.....lol

 

I would leave both windows cracked a few inches.....If it got too bad, I would wet a towel and hang it up over the vents.....That worked real well.....

 

You can go low tech, and wear a soft bandana around your face when you sleep.

That's what I do. The moisture from your breath gets trapped in the fabric and keeps your nose and throat from drying out.

 

You would be amazed how many drivers have no idea their trucks have cab filters. If you don't know about it, it's already disgustingly coated in dust and funk. I blow mine out monthly and it really should be blown out every other week or so. The difference between a clean and filthy cab filter is like night and day.

 

I have one similar to this. Sits on the cabinet in front of my head so the mist falls on me. Works awesome, runs off my inverter no problem, I refill water bottle from gallon bottles I buy at Walmart for .88 cents. I have a huge problem with my sinuses all my life, if it's winter I'm suffering as its too dry, sinus infections all the time. This works so good I have one at home. Can't recommend it enough.

I use to have the same issue with my old truck but my new one has a Webasto sleeper heater and the issue is solved.

 

I do the cab filter thing, but also leave a window down.
This probably has a lot to do with what part of the country you are sleeping in too.
