Both AC's will vent into the ceiling duct system, the front AC will send cool air into bedroom and if just the bedroom is working it will send cool air to front of coach through the ceiling vents.
The 2 AC has to be programed as the front AC both on cool.
You select the zones 1 & 2 by using the MODE button and the number will flash when you select zone 1 or 2. Once your in the zone the MODE button will select heatpump, if you have it, cool, furnace.
The control unit in AC 2 has to have the
dip switches set correctly for them to show up on comfort control.
If none of them show you may need a new tel wire cable connector or some cleaning of plugs in the AC control box on roof, plus the dip switches that Gary mentioned.
I would just try to set zone 2 for now maybe all you need to do.
If you have someone pull AC off roof
the foam seals have to be replaced.
