Sorry for the late update guys. We just came back from our first 3 nights camping trip.
As mentioned I drove the unit back to our RV dealer and they looked at it right away. The dealer did some tests on the roof with water and there was not water leak at all. The marks turned out to be some dirty powders and they were wiped clean with water. They suspected that it was a dirty ceiling board when it was installed and Quality Control did not pay attention to the details. The ceiling board material is either PVC or Plastic.
