We've had a couple of bad thunderstorms with heavy rain and high winds. Each time I've found a puddle of water in the center of the storage bay. Most obvious leak path is door gaskets. But they look good. Also took everything out and looked for a trail of water ingress, but found nothing. It's as if a cup of water was spilled. So just a puddle in the middle with no signs of water trail. Thoughts? BTW it's not a plumbing leak, I checked that.
