Randy, that's an impressive schematic! Makes me wish I had the earlier model so I could make full use of it!
If you've ever got used to using schematics to troubleshoot in an "earlier life", you know how lost you feel when you're pitched into a new layout (such as an RV) without one.
A lot of RV'ers are hands-on folks, and Phoenix would provide a great service by providing something like you (and, earlier, Keelhauler) created.
They undoubtedly have something similar for use at Elkhart--looks like it wouldn't be impossible to provide a print in the owner's literature for customers.
