Hey all,
New here and in planning stages of our build.
I’ve seen so many different diagrams and set ups online and have put together the attached. In theory my head says this is correct but would like to hear your thoughts / views on it.

I would remove the wire connecting the starter battery negative terminal to the DC-DC charger, since the DC-DC charger is already grounded to the negative bus bar. Then I would make sure the chassis ground that grounds the negative bus bar is the same ground point on the chassis that the starter battery is grounded to. Grounding components at multiple points on the chassis can cause problems.
