Congratulations on getting #428, the shortest Newell ever built with a Detroit Diesel Series 60. First, the dash air is the only one that runs off of the engine. The other AC units run off of 120 volt power, either when plugged into 50 amp shore power or running off the generator.
Since you have the smallest Newell built during that time period, I don't know how many AC units you have. They would be in the bays. You likely have a single 13.5 k btu AC that serves the bedroom and bath and a dual AC unit that serves the kitchen and salon. The compressor and condenser for each unit are in the bays. There should be a thermostat for the front AC, probably in the salon and one for the rear AC, probably in the bedroom. They are NOT tied together so if the rear AC is not turned on, you will not get any air out of the vents in the bedroom and likely the bath. If the front AC is not not turned on you will not get any air out of the vents that are located behind the valence panels that run above the windows from the kitchen up to the front overhead compartment. I have basement airs but they are the older Dometic units so mine may be somewhat different but you will need to have both thermostats turned to cool to get cold air out of all the AC vents except the dash vents.
