P25ct, if your unit is still in warranty, I would certainly take lots of photos with the date option turned on in the camera. Then send the dealer the photos and ask if they believe this is a warranty issue. Even if the dealer says no, and later it does become an issue you can prove it happened before the warranty ran out. If you are out of warranty...always let you wife go on the roof...
. Just kidding. I think you also might carefully and as accurately as possible, measure the distance from the floor to the ceiling in multiple places where it should be the same. Record this as well along with the location of the measurement; it will be very specific evidence if the ceiling is sagging as you suspect. Good luck
