We had a wet spot once, it was condensation, not a leak.
I guess it is POSSIBLE that there was condensation under the mattress in the front corner of the cabover. I had heaters cranked up to high to keep the water from freezing and it was REALLY cold outside. The heat would have risen to the cabover and the outside had lots of icicles so it was obvious that heat was escaping there.
But my gut says leak. The signs seem to be there--slight cracks in the caulking--edges darker behind the caulk. Blackened wetness in the front corner--mold sure grows fast! Just all the scary stuff that say LEAK! Maybe condensation added to the damage though.
