Water leak from hard rain

[pazahora]

When in rains hard and the back of my Thor Vegas 2017 faces the storm I have a leak in the floor bedroom. If the motorhome is sideways to the store, no leak. Where could the water come from?

Tail lights and clearance lights. It's a known issue on some of the coaches, can't remember which tho. I sealed mine just because.

I checked the back tail lights, and the rubber sealant is rotting away. I ordered the butyl tape, and already have the silicone glue. I just hope it does not rain up "my backside" until I get the tape!
