Downside to lower CO alarm?

CO poisoning is still not well explained to general public, but available knowledge is that it mix with most of the air, that is why sensor is recommended in mid-level.
I still think that it doesn't matter that much.
I am against combining the alarms as propane sensors work for long years (I tested 20 yo still working) when CO sensor has 10 years efficient life and should be replaced.
So if you keep the camper long, you will have dilemma in few years.
I also like the idea about 10 years batteries no matter what.
CO poisoning is "by absorption" what is another hard to figure out feature.
In my old house I had fireplace, that I was using heavy. At the time I had CO detector who would display value of 500, what is consider deadly, but for short time it lasted the detector did not start alarm.
Lastly I camped for almost 20 years before CO detectors become available and am still alive.
Just don't use range oven for comfort heating and make sure your furnace is in good condition.
Lot of owners use furnace heavily in cold climates, while never cleaning the burner.
For generator use, you suppose to have exhaust gas alarm, but those are still hard to get.
