What's still unclear to me is the source of the leak. If it was dry when closed but water still collected, it's not the tent that leaking. It's the door panel. If the door and seals are not installed correctly at the factory, or if the door is not closed correctly by the user, water gets in through the crack with the bunk end door closed.
I've heard that used to be a common problem. Because it was common I would attribute much of the problem to design flaw. I've also gotten the impression that the problem has been mitigated. It can't be completely prevented by the manufacturer because the user can contribute to the problem by leaving some of the tent stuck in the door, preventing a good seal.
If the trailer is new, not completely "seasoned" by getting the threads wet a few times (they swell up to seal the needle holes), and put away wet, the trapped water on the tent could leak through the seams into the interior of trailer.
Pop-ups will leak through the tent ends just the same as a hybrid. The difference when closed is the roof seals completely down on top of the trailer wall. On my old Coleman it overlapped some. There still can be a roof edge seal problem if not closed correctly, or not installed correctly at the factory.
