Mystery Leak on 2015 Melbourne 29d

[Samsara]

I post this hoping a more creative mind can figure this out. I have had a leak behind the passenger seat (behind the panel) since I purchased this rig 16 months ago. I can tell someone else tried to find it too by the unsuccessful caulking in the obvious spots. I have water tested many times and no leak until it rains. The curious part is that it needs to rain for about 28 minutes b4 it begins to leak. Trying to figure out if it is traveling or pooling somewhere. Attachment 1 Thoughts?

I would try to reseal everything on the outside and the roof of your unit first. There are some seals under the overhang front cap too that have been known to need redone.

My first check would be the cap seam on the roof, and while I was up there, I'd check all the marker lights.

I'm planning to Eternabond my cap seam for a semi-permanent, maintenance free seal. The application of Dicor on mine looks a bit dubious, and that's not a place you want to take chances...

If you can't locate the source of the leak try a pressure test, that will find the problem.

Thanks - checked lights but not cap seals.
