So, I got into the 'doing' part today and removed the Norcold N611RT. Went very smoothly, no issues at all. Measured my entry door and was very pleasantly surprised to see that I have 28" of clearance on width without removing the door frame, so it looks like the Norcold and the new fridge will go through no problem. That was my biggest concern, I guess I should have measured the entry door first, would have avoided a lot of 'thinking'.
Now that the fridge is out, true measurements are 23 1/2" width on trim, 24 1/2" inside width, 60" height (removing spacer panel above old fridge) and 24 1/5 depth - this means the new fridge will stick out by about 4". Not a bad compromise to double fridge capacity!
