Trying to find a Leak

[Suspenc3]

Hi everyone, I have a 2014 32TSBH that has been well taken care of over the years. I recently noticed a fairly bad leak in the corner of one of the slides, underneath the dinette. I’ve checked the exterior many times and can’t seem to locate where the water is getting in, have any of you had a leak similar to this?

Does it leak only when the slide is extended? If so, check your slide seals to make sure they are seating properly. Also get up on top and make sure the roof material on the slide itself and all the tape etc on top is in good condition. Also check your window screws... over time they can loosen up and water can get in through the window frames if they aren't sandwiched tight together like they should be.
