Well I'll state right off I don't have one but I want to install one. When I look at the
Nova Kool Installation Guide It does not state that you need outside vents. All it tells you is that it needs air flow at the bottom and at the top either in front or on the sides and it gives how much is needed. In fact a couple of them a RFU9000 and a RFU8820 do not require any additional vents as it is built in the fridge front flange.
It just seems when you are trying to keep as many outside openings down that the less you cut into the outside shell for insulation factor the better. Yea in the summer time you are adding that heat to the inside of the unit. It would seem the best would be to have outside vents for summer time and inside vents for winter (cold) camping. During the winter have panels that would fit into the openings and then in the summer you could take them off and let it vent to the outside. I'm also trying to keep the openings down from places that mud dabbers can make nests also. I have to tape up all the openings in my camper in the summer time when we are not using it to keep those buggers from building their nests. With the panels I could close it off when I'm not using it then.
