Ben: you are going through an experience similar to what most of us on this board have gone through. These coaches are very complex but as you become familiar with the logic of the systems and the associated hardware you will be able deal with most problems expeditiously. The questions you are asking are well thought out, lead to useful information, and the folks here are really willing to offer help. That's a nice combo.

Me? I learned my air system by spending hours under the coach tracing lines that run hither and yon (and back again it seemed). One of the things I learned from that was that Newell put together a well thought out system that has a helpful logic to it. As I came to understand that logic my troubleshooting and search for leaks got easier.

From the questions you've asked I'm confident that you will soon be promoted to guru. Yeah, initially there is so much to try to comprehend that it's outright intimidating. This is one of those cases where persistence pays big dividends. You will likely noodle around struggling to understand how this all works, I know I did. Then suddenly, smack upside the head, the lightbulb goes on and you get it. It feels like a wonderful miracle when that happens. Man does it feel good.
