I have had two different Jayco dealer service departments do the winterizing on my 2016 Eagle fifth wheel, and each time after dewinterizing, I had leaks. I have the residential Frigidair refrigerator and the manual says only winterize it using the air method, but the dealers have used antifreeze.
I'm going to do it myself and use air, so this discussion was very helpful. I think what happens is water gets trapped between the valves, so I will try cycling them in all the options.

This spring was the first time I have EVER had a water leak after winter. The same elbows you are all having issues with. I replaced with a heavier gauge material this Spring. What a PITA to get the panel out and to actually get to the broken parts. Little pin leaks in 3 of the elbows. I use the air method and since we have the washer I now use pink after the air as to get pink in the washer pump.
