I think there might be just a little confusion on this issue. From what I understand this may have been the case on some of the older 17's that had the large
fridge. Supposedly, that is why
Casita put in a larger window in the back of the 17 so it could be removed if necessary. I don't know this for a fact, but that is what I've heard.
Since I have an '89 (16') and may have to replace the original
fridge, I have checked. Mine can be replaced with the same sized unit.
If it concerns you, you can call
