On a pop-up or A-frame with the continuous run fridges you are in and out of the vents at least once a day because that's where the controls are. The high wall units have a larger fridge with controls inside (even more of a pain when the camper is folded down). When camping, I would usually keep the pins in the loose position for easy vent removal. When hooking up, turning the pins to the tight position was part of the "ready to tow checklist".
I keep/kept a dedicated straight slot stubby screwdriver in the driver door storage of the tow vehicle.
