The CO comes from your engine, which produces loads of it. Humans breathe out lots of moisture, another things that needs to be vented.

Again, if you can smell it, it's not CO.

We already told you to use MAX AC

Again, it's to keep you from passing out. Like I said, its still enough to keep dust and smells out.

So are you still having issues? I guess you'll have to buy an air purifier and drive around with it LOL.

Since I'm building this out as a camper, a CO detector is part of the equation.

Thanks for all of the replies. They've been a great help.

Happy trails,
