OP Here,
First thanks to all replied!
Second the reason I am considering doing this modification is that in my old 5th wheel I had to replace the cooling unit. I don't ever want to have to deal with that again. I also have been reading that refrigerators installed in slides are more likely to fail because of lack of ventilation.
Based on the responses here I am going to wait until I get the RV out of storage and see what my installation looks like before I order any parts. I may or may not need anything
Thanks again!
Dave
