I apologize. The Samsung refrigerator that I had installed in my '09 Diplomat 40SKQ was the RF18, not the RF197 as stated above. IIRC, the RF18 was the follow on model for the RF197. Very similar dimensions for both with some compressor improvement in the RF18.
I did consider a Fisher & Paykel (RF170A series). I know the F & P was significantly more expensive and, I believe that the F & P warranty would be voided unless I upgraded the inverter to pure sine wave. You can check the specific dimensions, but, IIRC, the F & P is inches shorter than the Samsung which would make the installation easier with the height constraint in the slideout.
Here's a .pdf giving some detail regarding my installation: refrigerator install.pdf
The installation was done by Alliance RV in Wildwood, FL. Alliance RV now operates as Lazydays. At the time I had mine done (early 2016), Alliance was doing about 1 a week.
