Rear Compartment Water Leak

[CaptRon]

The outside compartment on the rear starboard side of our 19ERD leaks a small amount of water. I'm assuming rainwater since the last trip involved driving through some heavy showers. I had the dealer replace the sealing gasket but I still get some water in there. I think it's too far aft to be affected by the wheel well leaks reported elsewhere.

Has anyone else had this issue and fixed it? Could water be coming in around the hatch trim somehow? or maybe the entry door trim?

Thanks
