Not related to your refrigerator, but I had to remove the covers off of my water heater to replace it on my SCR27 as it was about 1/2 to 3/4 of an inch too wide to get it out of the engine compartment.
So you may want to look at your refrigerator, perhaps you can remove (or un-bolt) some parts and/or covers to give you the extra room to be able to remove it. Or remove some trim from the cabin door for some extra room.
My 1990 Maxum was sold today. I had it less than one year, but it was good to me!
