As I remember, the culprit on my Passport for an occasional overhead drip was a hand rail leak... or possible a turning block up there. I pulled the entire overhead panels
down and waited for rain. It was the rainy season in florida
, so it didn't take long. But I just could not find the path of the water
... as it was so minimal. The creeping crack cure actually fixed it, or maybe when I went south shortly after that I didn't get enough rain for it to leak!
Those occasional slow leaks
can be a bitch.
