A refrigerator for recreational vehicles comprising a generally cubic cabinet having front, back and top sides along with absorbent-type refrigerating apparatus on the back side. A flap member adjustably mounted on the back side at a position above the refrigerating apparatus extends upwardly and outwardly from the cabinet into sealing engagement with the walls of the compartment in the recreational vehicle in which the refrigerator is installed. The configuration of the flap member and the mounting of the flap member so that it can readily be adjusted to a number of positions enhances the ability of the flap member to prevent gases created by the refrigerating apparatus from propagating into the living quarters of the recreational vehicle.
