Good advice.
With only six volts, any loss is a big one.
So use as big a wire as you can, never mind the theoretical specification.
Including, if you can, oversize the starter cables.
Run earth wires for everything, don't rely on chassis or bodywork.
The earth wires will carry the same current as the items they are serving.
I use one common earth point near the battery for the rearmost items, and one near the dashboard for the front end, and run substantial cables back to the battery, to avoid too much clutter at the battery itself.
