I remember back in the day, the assigments had an order, such as 10E Cmd 10F Tac, or 11H Cmd 11I Tac, sort of like Heartland or Metro. I lost track of the order, but remember someone posted a list a year or more ago, where it showed the commands and tacs per battalion and area. I can't find it now though.

This is what I have. Based on CalFire Monte Vista battalion areas and assumed County Fire Authority AORs within or around those areas. I cannot guarantee the accuracy of it though. It's gathered from info from the thread you mentioned, documents I've read, and general experience listening to RCS. It might be outdated or just flat wrong.
Batt 1/7 North County (Rainbow, Red Mtn, De Luz, Miller, Valley Center, Rincon, Del Dios)
CMD: 10C Tacs: 10D-10E
Batt 5/8 North/East County (Ramona, Witch Creek, Julian, Cuyamaca, Warner Springs, Puenta La Cruz, La Cima)
CMD: 10G Tacs: 10F-10H
Both of the Above areas share the rest of the Zone 10 Channels. Looks like 10I and 10L are command channels.
Batt 2/6 East County (MVU, Gillespie, Flinn Springs)
CMD: 11F Tacs: 11G-11H
Batt 3/4 South/East County (Lyons Valley, Dulzura, Potrero, Campo, White Star, Mccain Valley)
CMD: 11C Tacs: 11D-11E
Both of the above areas share the rest of the Zone 11 Channels. 11I and 11L are command channels.
As stated, 10A is Dispatch, 10B is Admin, 11A is the Travel channel. 10P and 11P are Emergency.
