Water leak

Hi I have a 2017 Kemerton xl,after bad weather at weekend had water coming in through courtesy light in cab

A total guess but I'd look at the seal of the rooflight, the roof slopes forward from there so any water coming in at that rooflight would run towards the front and possibly exiting through the courtesy light.

The panel above the shelf needs to be removed to see the place the water has come from. If your going to do a job the prep and to investigate the leak is most important .if your able to remove this or need help to do this just ask and I will help you .there are lots of places that may be your leak problem.you could also do my extra insulation mod above this panel and will also help stop the wet from the roof
