Boondocking and using a Generator while sleeping ???

Not too long ago, we ran our onboard generator non-stop for 6 days during a storm caused power outage with no CO increase indicated on our two CO detector displays. We did install our Gen-turi though. We wouldn't normally run it continuously for ourselves, but we were also powering the TT's on either side of us, one with a fellow on oxygen that needed his concentrator powered 24/7.
