I'm gonna throw out my idea as an electrician. Without looking at any wiring, I would assume the battery top right would be the chassis battery.
I would assume that the 2 lower side by side batteries to be the house batteries. You would usually find these under the steps in a more modern rig or in an electric bay down one side or the other. They could have been Two 12 volts in parallel but I would think they were Two 6 volts in series for better efficiency.
That's just a dumb electricians take on it. I got any takers??
