I've had a few camper shells and don't want to go that route. Thus why I'm not looking for opinions. For the generator while camping, I want to open the cover and tailgate, and fire it up in the bed. A tri-fold cover is easy to remove if I need to haul brush, etc. I agree it's probably not that big of a deal.
There are probably plenty of small vents that you could use. One that comes to mind is the round plastic ones used to vent RV battery boxes. Sure there are many more. Mount several thru the front wall of the truck bed, near the floor. Since the tailgate does not have any weather stripping, air will easily flow around the sides and bottom of the tailgate. The combo should provide adequate ventilation.
