Water intrusion in rear cargo area?

[FW_Z71Burb]

Happy Saturday and anniversary of D-Day y’all
The burb started to develop a STANK the last few days. Thought it was a dirty diaper left behind somewhere under the 2nd row but that ain’t it. Finally pulled up the rear cargo mat and the right side of the rear cargo area is moist.

We’ve gotten a lot of rain in Texas but I don’t see any signs of water intrusion. Weatherstripping on the rear hatch lols good. Is this a typical area for water intrusion? Does the rear AC on this side leak or condense?

Thanks in advance

Umm. I painted the sail panels on both Suburbans, and one had some missing wheatherstripping. I put some rtv around it.

Maybe that's where the water may coming in from? Let me see if I can find some photos?

Here's the photo. Driver's side sail panel. I can't remember if I had any water getting inside on this suburban or not prior to me noticing this?
