On our 31W there is a shutoff for the icemaker, so I closed it and removed the icemaker line to drain it, not a drop came out. I imagine the line would need to be disconnected at the top off the fridge to drain. So I reconnected the line and winterized the entire RV, by the time I was done I had antifreeze in the ice bucket so I know the line has antifreeze in it. We'll see how that works, first time with an icemaker for me also...
