Why would you want to fix something that should be fixed under warranty?

Here is some information that may help you. I agree with doing things yourself if you can, waiting for a dealer to attempt a fix and then waiting for the next soaking rain to see if it works is a fools game.
Hey Ronc, Yeah that's a good thought, It is level according to the automatic leveling system? I do see that the slide-out is not level though, there is a larger gap at the bottom of the slide than at the top. I'm guessing that the weight of the slide-out in the closed position causes it to sag and tilt slightly. Anyway It's supposed to stop raining here by tomorrow, so I'll double check it for level and after I can get a good look at the seals I'll see if there are any adjustments that can be made to square up the slide? It's leaking at about 1 drop every 10 seconds so I have a bucket under it for now.
I had a few drips also on my trailer when closed. took me a while to figure out where is was coming from. I checked the slide roof membrane, corners etc and could not stop the leak.
There is a 4'' molding on the exterior wall at the bottom of the slide which has caulking along at the top joint. Well, even though the joint seemed to be perfect visually, there was a part that was darker because dust was stuck in a micro crack. Re caulked over and infiltration stopped. It really doesn't take much for water to infiltrate. In my case, the water penetrated from there and dropped on a horizontal 4'' plastic band (which I think is a continuation part of the side walls) that runs under the slide and that is glued on the insulation and under belly. Once the slide was closed, the water was following that horizontal part all the way to the open end and was dripping in the middle on the trailer

Good find Lynnmor! This looks like the exact same thing I am dealing with (Same slide, same location)! And thanks to all you guys for your helpful advice. The rain has stopped today, so I'll get out there and complete diagnosis & hopefully repair it. I'll take some pictures but sometimes these little details are tough to see. Thank you!!
I "THINK" I may have it fixed? We'll see the next time it rains? I used the caulking I had left over from my previous trailer, (grey) it's the good stuff, brand name Sikaflex. I can't seem to get the AFTER pic to load without rotating left? BEFORE AFTER
It's ugly but it's sealed as shown and along the full length of the top of the track.
