Small amount of water on top of black tank

[hugh]

I was doing some maintenance under the bed in our 21c, and happened to notice a small amount of water sitting on top of the black tank. There was no odor, and as far as I can tell, it wasn't the result of any sort of toilet leak. (No amount of flushing the toilet or spraying the toilet area with water caused any more leakage)

Anyone have any guesses / suggestions on what the source of this could be? My best guess so far is some rain leaking in via the bathroom fan, running down the outside of the shower stall, and dripping onto the tank. (We had some rain a day or two before I noticed the water)


Thanks,
Hugh

Was the tank full or empty? If full and humidity was right, I would guess there could be condensation as the air cooled down at night...

Interesting. I hadn't considered that it could just be some pooled condensation. The tank was about half-way full, and it was quite humid given the rain during the trip.


Thanks for the suggestion.
