I just thought I'd describe this and see if I get some useful feedback.
2014 JKU, factory color matched hardtop. When it rains, the floorboard on passenger side gets soaked. I am sure the source is the top edge of the door, near the pillar, because I've found water on the inside up there, down the inner door, on the speaker, pooled on the floor. It's not a daily driver, I don't drive it when it's raining, so I've only seen the results, not the actual leak as it's happening. The "fit and finish" of the passenger door appears to be identical to the drivers door. The condition and arrangement of the weather strip appears to be identical to the other side.
