I was down at my new Axis the other day and did this experiment:
With the chassis batteries showing 12.6 volts, I started the generator. A few minutes later I checked and the converter was charging at a few amps and the coach batteries were at 13.5 V and so was the chassis battery.
Obviously the BIM had connected the two since the coach was charging, ie its voltage was above 13 V.
So this winter my solar panel should keep both house and chassis batteries charged up even though it is only connected to the coach batteries.
