2016 Thor Chateau 31w leaking on bottom corner of slides.

We have a 2016 Thor Chateau 31w that is still under factory warranty. We have had issues with seeing daylight and leaking on the bottom corners of the wall slide from day 1. We are mainly having problems when the slide is in. Itís looks like the drain cups are uneven and they are filling up with water and leaking in the camper. Dealer tried to fix several times and they said that they contacted Thor for a solution. It seems like they keep adding pieces of rubber to it, and this is not fixing the problem. This coach has been a nightmare since we have bought it New 6 months ago. Too many problems to list.....
Have any of you experienced this? This seems like a major design flaw. We have been very disappointed with Thor so far. We have sent the dealer and Thor videos of it leaking and still not fixed.

Drip rail ordered

I just ordered some trim lok drain rail that I will run along the top rail near the roof. Hopefully this will solve the problem.

It has a drain cup that is leaning backwards, this fills up with water and then leaks inside the coach. Should this drain cup be level or draining forward? Is this something that has to be fixed at the factory, or can my dealer handle it? Please let me know what you guys think.
Thanks

I had the same thing! At the PDI I saw daylight at the bottom of the slide when it was closed. The issue, fixed by the dealer, was an outside body molding that should have stopped just before the slide but wasn't. When the slide was in it overlapped the molding instead of sealing against the side. The fix was to remove the molding cap, cut back the molding with a dremel tool and reset the cap with caulking.

Now that you've had the ongoing leak, water damage to the subfloor seems certain. Check for swelling. This has to be repaired soon.

Realise this post is a little old, but we have just discovered the same or similar issue with our 2017 31W. It is out of warrantee so trying to figure out the best way of remedying the situation. When we store our coach in the compound and the slide is in it leaks. When we are away and the slide is out we don't have any problems even when there is torrential rain. I could do with a little more info from those of you that have experienced this issue just so I know whether I can fix it myself or need to get some outside help.

Check the outside trim pieces on the outside of the slide and silicone if needed. Water was getting in that way. The dealer also adjusted the bar at the bottom of the slide that allows it to close tighter. We will sometimes still get a little water. Too frustrating. It has gotten better, but still not great.

Thanks - will check that out. The water comes in under the slide for sure, so maybe the answer is to get the bar adjusted as you suggest to make a tighter seal.
