I am not sure from your description just where the leak you see is.  When you say 'high up' do you mean at the shower head or somewhere else.  Your description didn't sound like it was a drain.

It's quite possible that the leak isn't from the pipes themselves but from the drain area of the shower.
Check the access panel, which is probably hard to reach, but usually from the bedroom. You should be able to see under the base pan from there. If the leak is from the drain area leaking, you can use one of these.

They install entirely from the top, and will save you a lot of hours trying to get access from below.

If you have a cracked pipe, you may have to create an access from the wheel well or remove the shower entirely. Both have been done by others on the forum, a good search should find those examples.

Thank kwikitex. Removed that panel in the bedroom as well as under the toilet. Used the bore scope i forgot about and zero water under the shower pan, nor from the pex lines running up to the mixer. Also zero water under the toilet area. Nor along the shower drain pipe. I was unable to get the scope pointed down where the shower pipe links in the sink drain pipe. Color me confused.

Also, the water that is on the ground did not have the grey tank stink.

Final conclusion. In the end, it ended up being a leaky fill valve. It happened again when I hooked up to city water. I made dang sure i never touched the fill button.

And what do you know. The next morning the nearly empty tank wasn't empty any longer. The overflow had a very small but constant dribble. So a valve rebuild or replacement is on the docket when we land in Tucson next week.

Jerry have you been using a pressure regulator. Leaks will happen without one my pressure is quite hi

Yep! set at 45-50 psi.

I imagine that our fill valve is old and crusted up with hard water deposits. We spend most of our time in fairly dry places that have very hard water. We do use a softener, But that isn't a cure for all the years prior.

We have owned this coach since 2015 and who knows if the fill valve was ever rebuilt or replaced prior to our time. As water 'leaks" go. This is of course quite minor and has an easy work around till we land at Justin's on Dec 10th.

I took our water fill apart today. No rebuild parts needed on ours.

When first taking it apart I saw no apparent debris, but when I swished all non electric parts  around  in the sink full of water I filled before turning the water off, multiple small/tiny  pieces discovered. Note direction of water flow and take a pic of it mounted before removing and it's a fairly easy job. 

I'll know tomorrow if the seepage slowly filling the tank is resolved (I think it will be).

I would feel better if I had a spare valve "just in case" or even a manual ball valve.

Carol said it best a few years ago about the fancy toilets. "I don't want a turbo turd 2000 electric toilet"

And, of course there is always the KISS solution of replace it with a manual ball valve!

Still seeping with water fill valve.  I found a older post by Michelle with great photos that shows complete disassembly of the valve.  I didn't tear down that far, but probably will today.

The fill valves are pretty much standard irrigation valves.  The tough thing is that the assembly is a 12V solenoid model and most irrigation valves are now 24V solenoid ones so a drop-in replacement can be challenging to source.

Also, 199x-2001-ish era coaches have a different fill valve than 2002 and later.

Might need a change of subject line for this thread, or perhaps a breakout to a new thread?
