Greetings to you too Tater65! Thank you for your inquiry and for your interest in the ENERGY STAR® Qualified LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView™ Door-in-Door® Refrigerator, Model # LUPXS3186N. Regrettably, LG has not made any announcements about any plans to release a version of this refrigerator that would feature the ThinQ™ Door along with the CoolGuard™ stainless steel panel interior that helps maintain cold air while adding a premium look. If LG has plans on that they will typically put out a press release announcing it...^IFV

Hi Colek. Regrettably, the ENERGY STAR® Qualified LG SIGNATURE 31 cu. ft. Smart wi-fi Enabled InstaView™ Door-in-Door® Refrigerator, Model # LUPXS3186N does not come in other sizes. What you need is the measurement from the floor to the bottom of the cabinet above your current refrigerator and the depth of that cabinet. Typically, standard overhead cabinets are 12 or 13 inches deep except for microwave cabinets which are 15 to 18 inches deep so they can accommodate most standard microwave sizes. Cabinets placed above a refrigerator are also slightly deeper and typically measure 24 inches deep. This refrigerator has a height of 69" to the top of its case and the recommended installation clearance above the refrigerator is 1 inch so if your cabinet is a standard cabinet with a depth of 24" and has a 70" clearance between the floor and the bottom of the cabinet, it will fit. It has a height of 70 1/4" to the top of the door hinges, but again, if your cabinet has a depth of 24", that will not be an issue...^IFV
Yes, the door in door will hold a gallon of milk. ^CP
