If the caulking on the roof around the skylight is not compromised your leak is not from the skylight. Where my roof track was leaking was at a joint in the track. That is where the caulking was missing. I did not realize that signs of the leak were there when I bought the coach last year in Ft Myers. didn't realize the skylight in the shower was leaking because the water was down in between the exterior and interior wall. Now the wallpaper in the closet beside the shower is ripply and coming off as well the wall is spongy. I'm going to reseal the leaky skylight.
