For a van conversion.

Is 40A Breaker on 6mm2 pushing it a little?

Diesel Heater is on its separate circuit, for safety.

No RCD/Consumer on multiplus shore inlet, I've heard this can cause headaches.

One thing I haven't drawn yet though.. I was considering charging the starter battery from the multiplus trickle, would that be any more complicated than just joining it to the starter battery positive?

Indeed, 6mm² is a bit small for my liking. Why not go with 10mm² since this is already used elsewhere.

The MultiPlus' negative is referenced to the same ground as the start battery, so it's easy enough to run a wire over to the start battery for trickle charging.

I definitely would, but I don't think mppt 100/20 can accept 10mm² - datasheet says 6mm² max
