Bunk Windows. Safe At Idle?

I always open my vents when I park. You are fine to have your vent windows open. You do realize Cascadias have two vents located on the back of the cab that let outside air in. The fresh air comes in thru inline where the top bunk sits when it is down. Look at the back wall in the middle.

I don’t see anything up here. Except heat waves, like a mirage.

I will send you some weather from Iowa to cool you off.

Ouch. That is cold

Just gotta make it to Sunday. We should hit 50 degrees!

I’m up in this cold snap too... It got to 28 today in quebec and I thought a heat wave was here. Starting tonight going negative over here. I hate idling my truck, but no way am I shutting it off this cold. I already told my dispatcher too find me something southbound, I need to thaw out

I sleep with my small windows open every night, I also run the bunk heater to makeup the difference so it's not to cold. So far I'm fine.

It's Carbon Monoxide (CO), not Carbon Dioxide (CO2).
