Have the original fridge out of the cabinet. Looks like if I remove everything, front doors and all the rear components, along with the bottom rail, I can get the fridge out without removing the sliding cabin doors.
May wait a few months to install the fridge, as there's plenty of other projects. Had to remove the fridge to replace the head waste pipe going back to the engine bay.
Will take lots of pictures when I remove the sliding doors. Any lessons learned, apart from what's already been posted, would be appreciated.
