Leaky shower plumbing?

[kcox4434]

We noticed water (it was soapy) dripping from underneath the rear after I had showered. After taking everything out of the back hatch and wiggling around, we came to the conclusion that the 'U'shape plumbing was leaking onto the aluminum underbelly and dripping down by the stabilizer jacks. Is there a way to fix this ourselves or should we make an appointment at Airstream? We are currently on the Oregon coast without many tools...

Also, there are no leaks on the subfloor, it's all coming from the drain-if that makes sense.

Sounds like the "P" trap. Can you tell if it is leaking at the shower connection? Perhaps the trap is cracked because it didn't get winterized.

Not sure how to post a new plumbing question, so I am trying this "reply"
We have a leak in the shower behind the wall, and we have been told by the Airstream Customer Support that in order to get to the lines, the "shubby wall" must be removed and we can then access to repair the line (hot water)
There is a stress crack that is spraying water up the wall and straight down to the underbelly, so at least no water evident in the shower flooring.
We have a 2013 Flying Cloud 20 ft. with no visable access to this. HELP
