Well it really wasn't good news, but at least I have traced out all the plumbing....
- The "Galley" gray tank (Tank 2 on monitor) does indeed take all water from the Kitchen Sink and Shower. This doesn't look to be a mistake either, has to do with tank locations and fixture drain locations.
- The "Bathroom" gray tank (Tank 1 on monitor) take all water from the bathroom sink and the Washer (if you have one).
Think I will be installing a transfer pump next year if we have challenges with water management. We have been out camping now for almost 3 weeks with either no hook-ups or electric only and been managing ok with just the two of us.
Important note for those that are looking at the 38FL - We were never told this - not a huge issue but we should have been informed of the configuration.
