Thanks for the additional information Justin. The 2007 model years coaches were #787-816 (20 coaches) and #1200-1214 (15 coaches). That is good to know that the coaches starting with #1200 screens can be upgraded and that #816 and prior would have to be converted to RV-C. I am surprised that the inverters would have to be changed out as well since that would significantly increase the costs.

I am honored to have been able to add something to the forum! 

I don't think it was definitive that the inverters needed to be changed out, but probably needed to be capable of sending/receiving info via RV-C. I would bet that most inverters after 2005 would be capable of passing the needed info.

One more thing I can add on the RV-C system. Also according to Silverleaf, the system of that vintage was capable of doing quite a bit more than what Newell was using at the time, so they can be expanded to include additional features with a bit of wiring(if you really wanted to  )
