On my previous 5th wheel the refrigerator quit working. I pulled the frig and replaced the cooling unit with a Amish rebuilt unit. Purchased it here with fast shipping and great service when I called for clarification on instructions.
RV Cooling WarehouseMy unit was less than $600. I had to pay up front an additional $100 that was refunded as soon as they got my old unit back.
I was able to do this repair myself and I am disabled from several strokes. I did get help when pulling the refrigerator placing the new cooling unit and putting frig back in. I won't assume anything but if you are reasonably healthy and have a second set of hands for help and can read instructions this is something you could do in a weekend at most if not quicker.
If you are being quoted $2000 for repairs I would look elsewhere. They are replacing the entire frig not just the cooling unit. Your frig's other parts are probably fine and you don't have to replace the entire thing just the cooling unit.
As a side note we traded that 5th wheel sight unseen last year on a brand new unit. When we returned a week later to complete the deal they didn't really look at it and definetly did not test anything on it. But I did show them photos of it pointing out issues as well as the fact it had a brand new refrigerator.
Good luck and enjoy your new 5th wheel!
