Just as an FYI TMag, but if you have to remove the refrigerator, it probably involves removing the doors. We have a 2010 MS 38TKSB3 in which we replaced the original RV fridge with a Samsung residential unit. The doors even had to come off to get through the RV entry door.
To aid in putting in the residential fridge, we had a 4-wheel furniture dolly and I made an "insert" that would fit into the "opening" between the 2x4's at the sides. That dolly and insert was just right to lift the refrigerator to the height of the compartment where the fridge was to go. It was just a matter of moving the fridge around the end of the peninsula counter and get the left side of the fridge into the compartment and then swing in the right side of the fridge.
Here are pictures of the 4-wheel dolly and insert.
As an additional FYI, that same dolly system worked well when we needed to replace the washing machine. That was also near the same height to match the floor of the washer/dryer cabinet floor and trim. It let us remove the washer from the cabinet and then get a two wheel dolly under it to get it down the stairs.
