Google also links to a dead url, and when you search the NFPA for their most recent Carbon Monoxide Safety Tips it says that you should follow the manufacturers guidelines for the height you should install a CO monitor at.
My whole life, including when the Fire Department came to school and did a presentation and had us run through the simulated burning trailer, every instruction manual I have ever read for a CO alarm and everyone I have ever talked to about this all insisted CO alarms be installed near ground level.
How is that possible? Did CO Alarm manufacturers just get it wrong when CO Alarms were becoming more widespread a decade and a half ago and everyone just parrotted what they were saying without checking? I can even remember news segments on CO danger and needing to install the alarms near the ground.
Yeah the density of carbon monoxide is very close to the density of N2 so it stays fairly well mixed unless you have extremely still air. What matters most is having the detector near where you sleep.

That being said: Damn, you are actually correct.
