Hi,
I have an 04 Winnebago Adventurer 33v and have not had any leak problems. I suspect it must be the gasket on the rear of the slide that may be causing the problem.
When the slide is open check the rubber gasket around the slide and make sure it is secureand soft. I would also make sure you hold the retract button for at least 4 seconds after it retracts to make a good seal.
Is it possible it was raining when you closed the slide and that the water came it under the awning that is on that slide?
Lastly I woyuld use a hose to spray the area to know where the water is coming in. You can do that by having someone on the hose and someone inside to see where it is coming in.
Good Luck!
