You are correct. I had the same issue with the factory door seal not doing the job and had a few leaks as well as some wind noise. One spot was at the upper front corner of the driers door and on the passenger door water would follow it down the door and drip into the cab at the bottom. I went to the local hardware store and picked up some 3/8 thick by 3/4" wide black (Truck cap/Camper style) foam tape and ran it down the entire top inside the door edge. No more leaks.
