Where did the water go?

Here is another question to the group - you know 5th wheels are strange animals - my best friend bought a new 36FBTS just like ours.
When he puts the pick up line in his water bottle the next morning all of the water is gone and the pump is turned off. Cannot figure out where the water is going because there is none on the ground or have not found any wet spots anywhere - really weird

Can't help with the water situation, but what a good idea to mount the hanging rack mechanisms on the walls of the basement....I'll be doing that to our basement soon...
