The answer of course is that the dryer itself has a foam plug to keep bad stuff out. I know on my coach the plug that is supposed to seal against road dust or whatever else might come back up the dryer vent hose is far from a hermetic seal and I doubt that CO, or soot, or even diesel fuel fumes would be stopped.
To Joe's situation, I recommend treating the generator box as space that needs to be vented outside, it needs to be ventilated for 30 seconds or so before the generator is started, and the generator box needs to be isolated to the maximum extent possible from other bays and especially the living area.
I don't want to suggest the ventialtion fan can be eliminated, but upon generator start it can be turned off so that the box is a negative pressure area due to the generator air intake being inside the box and drawing in a large enough air flow to literally pull any fumes into and through the generator engine.
But no dryer vents. What an obvious path for CO from a defective exhaust pipe to travel into the living area of the coach.
