Yeah, me three on the don't understand the last two. But, typically, the grounding for both the chassis and house batteries go right to the frame, fairly close to the batteries themselves but, not always. As for the positives, when it comes to the house batts, the positive may have at least two large leads from the batteries.
One will go right to the inverter or, inverter/charger. The second one should at least go to a junction block where from there, it gets distributed to various fuse panels, relays and such to power up the coach's side of 12V ops. And, depending on the particulars of the make and model of the coach, you might have a third lead that will go to the starter on the generator. That way, if the chassis batteries are dead from sitting or, whatever reason, the generator should be able to start and, with the help of a charger of some sort, (many coaches, year/make/models are not equipped from the factory to charge the chassis batteries while on shore power or, generator power)be able to put enough charge into the chassis batteries to fire the beast up.
And of course, many coaches have capability of both sets of batteries being linked together via the "Battery Boost solenoid" which is activated by the toggle on the dash. I don't know if any of this helps but, I thought I'd throw it in for good measure.
