CO is the silent killer, it will get you during the day, while sitting in a closed up RV.
You don't have to be sleeping, it will do that for you.
The only chance you have is a CO detector.
There are many warning signs of carbon monoxide poisoning if you're awake to recognize them. They include dull headache, weakness, dizziness, shortness of breath and nausea.
In addition, confusion and loss of consciousness are two other symptoms. If your CO sensor goes off while sleeping but you don't fully wake up due to confusion already setting in then you're in trouble.
