Water line break in 2013 Roadtrek 210 P shower

[Diver007]

I have a 2013 Roadtrek 210 P. After taking it out of storage from the winter I have an apparently broken water line leading to the toilet on the left side. I don't see any access panel or a way to get to the water line. Has anyone ever had this problem or know how to fix it? I'd appreciate any help.

My ‘12 190 has a cubby door under the toilet platform. In there perhaps?

In my 2007 Roadtrek Agile there is some wood paneling held in place with screws. Removing these allowed access to the water supply to the shower.
