Yeah, the Dometic site and manuals don't exactly make it easy to design a system.
I converted my front unit which had manual controls over to the zone control, so I had to get a control box and new interior air box.
These are the main pieces I bought for my system:
B59516 Brisk Air II 15k
3105935.039 quick cool air package ducted return
3314082.011 white CCC2 thermostat
3312020.000 2 control boxes/kits
3314850.000 non ducted air box for front unit.
Oh, and you need a remote temp sensor for each zone.
Then a spool of nice conductor wire for my new 12vdc line to the main unit.
2ea 25ft RJ11 telephone wire (4 conductor)
Once I understood that the Dometic CCC controls system was CANBUS, it made it a little easier to understand the layout of the whole thing. The phone cable is for communication between the control boxes and the thermostat, and also supplies the 12v from the main control box to the auxillary. (for me that was my front system).
The hardest part of the whole thing was running the wires from thermostat to the main ac and from the main ac to the front unit. I did manage to get a lot of wire ran up through the middle of the unit, in the wall between the living area and the bathroom, where all the other main bundles were routed, and going to the front from there was also not to tough... but trying to figure out how I was going to span that 8+ ft distance to the main unit was about impossible... till I decided to route my new wires inside the cooling duct... it was a spark of brilliance, I'll admit... hahaha... but it really did make it so much easier.
