I have a residential refrigerator in the truck camper, kept the rooftop vent. The refrigerator needs the air circulation (cooling tubes are in the sides and top of the refrigerator) AND I have cables running thru the vent for the inverter.
I have a 13cf upright freezer and stacked two 4.4Cf dorm type refrigerators in my bus. These both have a vent at the back to allow heat to dissipate. Residential units do have heat build up and few refrigerators have the old style "radiator coils" on the back. They tend to be build against the metal skin of the appliance cabinet. In the case of freezer doors (both dedicated and ref/fzr combo units) a "loop" of tubing is run around the door opening to help in preventing up icing at the gasket. This is why there is supposed to be a 2 inch (or more) air space on the sides and top of residential refrigerators and upright freezers. Keep the roof top vent.
