You know, I have had -0- issues with my factory water filter, (2015 23SS) But the more I think about this, And the more I read, even with no issues (Yet) I think the external filter is the way to go. If nothing else because the filter is such I pain in the #$% to even get to. I find myself twisted, contorted and I have yet to not make a mess with it. I'm thinking I will remove mine as well, then I don't have to worry about winterizing, Making sure its not full but has enough pink, yada,yada. And BTW, the filters for the factory water filter are not cheap either.
