I just spoke with Cummins Support
They say that the EC-30 does have a software option to Prime Genny for (x) seconds duration if needed based on the design of the system (location of Gas tank to Genset etc.)
So The ACE nails it again; so what else is new 
They further state by Default this feature is turned OFF. (Cummins Onan EC-30)
They stated I did not need due to proximity of tank to genset for my coach and was concerned that I was wanting to change the setting ( I don't) despite me telling them multiple times my system was working perfectly; I guess they struggle with someone calling when everything was working
They also confirmed that Priming should NOT be required every time (design / location of genset notwithstanding). Genset should start 3 - 5 seconds, it is their opinion at least the support person I talked to today; that anyone that has to Prime;
it is because they are not using the Genset, or exercising properly.
Conclusion: If I had an RV that Genset was not in close proximity of gas tank and I had to prime every time that would be considered as normal to have to manually prime. If that same coach had an AGS, it would need to be programmed (likely with Cummins Onan help) so if you need the AGS to work properly it would know to Prime every time automatically.
For me this bewilderment has now been resolved. I guess I just got lucky with a design that has the Genset 30" inches away from Gas Tank
