Bunk heaters & humidity

My APU will run the fan at the same time as the heater, and if it's cold outside the incoming cold air seems to keep the humidity at a proper level as well as providing fresh air

 

You can also buy a Vic's humidifier

 

Do not select the windshield defrost setting on your HVAC. On this setting, it engages the a/c which of course, is a de-humidifier. Select face vents or floor vents.
All the above suggestions are awesome too. I like the essential oils mister idea especially.

 

I was in Wisconsin back in December. I remember driving past several Culver's feeling hunger pangs as I drove on. But I didn't stop at one since none were attached to even a small truck stop. That I was able to see, anyway (it was dark out).

Judging by your posted photo, I have surmised that you know of a spot where one can park a truck and acquire Culver's ice cream cup swagger.

Would you mind cluing me in?

Much obliged.

 

Buy a travel humidifier.

 

Oh, that's wet paper towels. I really wasn't sure what that was but I was thinking something totally different and that would definitely render any concerns of moisture in the cabin moot putting a cup of what that LOOKED like in front of the vent.
