Over the years I heard quite a bit about deaths due generator set up wrong.
I am not talking about forum rumors, but about ranger telling me "last month couple died on neighborhood campground"
I wonder what area require generator overnight.
Even in California nights are pretty cool and worse nigh shutting off AC at 10PM makes it comfortable.
That said, would I have to do it, I would get at least 2 CO detectors, make sure the generator fumes go with the breeze away from RV, or install one of those chimneys that are required on lot of campgrounds.
