Contacted AS Customer service for info on wiring diagrams - wanted to attached items to the inside shell and not hit a wire. They were very helpful, send a very detailed wiring diagram and also a structural set of drawings for my 25-ft EB. Would be glad to share with anyone (Will try to attached wiring and structural drawings file but not sure if will come with this post...). Send me a note and I will forward the wiring and structural drawings.
Below are a couple youtube videos that also came.
