[Solved] Water fill leak - '95 Roadtrek 190 Versatile Dodge

Great news! VE3ESN's suggestion led me to the problem.

The gravity fill flex tube was shredded all to pieces.

If they had tested the system they must have tested the city water fill and not the gravity fill.

Should be a fairly simple fix! Except I'm not quite sure the best way to get under there.

Anyone know the best way to access the top of the tank there? The opening from the gravity fill thing doesn't seem like quite enough of an opening to undo the connection at the tank itself.

Thanks in advance for any help!
