First certainly glad you are ok... Detectors work for something we can't smell/detect ourselves - and a reason to insure we all test our detectors... and maybe add one.
It is CO (carbon monoxide), and not CO2 (carbon dioxide) that is the killer. And it is not heavier than air - it is slightly lighter and it mixes quite well into the air unfortunately so can appear at any level... (CO2 is heavier than air - but not what we are concerned with).
In RV's the supplied CO detectors are typically near the floor because they are also LP detectors - and LP is heavier than air.
The lack of a tailpipe on the genny was a huge contributor in my opinion... A functioning tailpipe wouldn't release CO directly under the RV to come in through cracks... Sealing them up certainly doesn't hurt..
A genturi type exhaust that runs up above the roof line is even better... Of course still requires no exhaust leaks below.
I lost the tailpipe on my 2000 Infinity when is was about 12 years old... Happened to notice it on a 'walk around' - only one pipe where the two exhausts used to be. Had an auto shop create a new one to replace.
