Slide out leak in outside corner

[Bbrown10]

Help!!! We have a 2014 Georgetown XL360. About a week ago, we pulled the couch out to have it reupholstered. We noticed mildew and wet spot in the front corner(outside button) of the slide out. Since then, we tried to diagnose it in every way possible. We have placed tape for a run off on the front of the slide out, we have re-silicone all around the slides including around the screws, and nothing has stop the water from coming in. We’ve been into rain storms in the Last few days and wake up to a soaked corner. We put the slide out in during one of the storms, and it did not get wet. So, it’s only getting wet when the slide out is out! Please help! Does anyone have any suggestions on that what this could be? We checked the windows no water, we check the walls, no water. It’s about a 18” x 18” square in the corner of the front big slide out. It does affect the wall about 3 inches up the wall but we think that from the floor getting wet. See image attached. Other than that, it doesn’t look like the water is coming down the wall. We are at a loss!

You didn't say of you have a slide topper or not, It may be water collecting on the top of the slide and running down the gasket then entering where the gasket is not sealing at the bottom of the wall. Check the outside and inside seals at the bottom of the slide box.

Yes, we do have awnings over the slides.
