I will agree that the CO Deaths all have several things in common
Most common source is a PORTABLE generator or a neighbor's generator (I've had CO from a neighbor set off ye old alarm)
NONE, not one, was from an ON Board Generator with a Gen-Turi. NOT ONE.
Fact set 2
When My RV was new 2 hours of On-Board and BEEP BEEP BEEP went the alarm Unless I was driving then at 55mph the fumes never reached the inside of the RV
WITH THE GEN=Turi.. 25 hours and not a peep out of the alarm
Fact 3
Some folks yammer about how with the Gen-turi releasing the exhaust fumes near the roof "The air conditioner can suck it in".. THEY ARE LIARS. Period
Oh some models of Fantastic Fan Can "Suck" but just set the fan on BLOW and you wont' have that problem. (exhaust)
