You may have a couple of problems:
Is the door big enough to remove the current refrigerator and install a new one? If not it will have to go out a window or the slide will have to be completely removed.
Looking on Lowes and Home Depot web sites there are numerous counter depth 33 inch wide refrigerators. In fact this one is what came in my 2021 Cougar. (

Make sure that if you do get the residential unit installed that you have some way to keep it stationary. Mine has brackets along the sides and a piece of metal that crosses the front between the refrigerator and freezer doors to keep the unit from falling out/over. You might want to visit a dealership and tour a couple of models that have residential fridges to see how they anchor them.
