Regarding Multiplex Interface Systems such as CZone, etc.

[Re-Pete]

Does anyone have any experience with the kind of multiplex control systems that Airstream and most higher end RV makers are installing in their upper end models. Airstream is currently (2019) installing the CZone system. I'm interested in including such a system in my rebuild (92 Excella Classic), but I've tried to get info over the winter and I'm getting little to know traction in my attempts to find a provider. I got CZone contact info from AS and the CZone website, but The only folks I could talk to at CZone were techs, nice helpful guys, but unable to help me as far as how I might obtain the system, support for installation, etc. Could not get sales or upper management to respond to emails or phone messages. I've had similar and white luck with other brands. FRUSTRATING.
