Well after two years of trying to stop the leak inside my 2016 Champagne I'm asking if anyone has had success in stopping the same type leak. This only happens when there is blowing rain. Here is a list of what I have had done so far to try and fix it.
1. Had rear air conditioner removed and scoped to see if water has leaked into the ducts, nothing found.
2. Had new air conditioner gasket installed and four bolts sealed.
3. Had J rails removed cleaned and resealed including bolts sealed.
4. Had J rails opened at each end, as per Orvan .
5. Had complete roof gone over by two repair shops looking for any leaks or concerns, none found.
Has anyone found a solution? Going with a pressure test next and/or taking it to Orvan up in Indiana to see what he can find. Getting desperate, any suggestions welcome. Thanks in advance.
