Following on from this - it has happened again where I start the van and the EcoFlow doesn’t start trickle charging. But on another occasion it did - I didn’t touch the unit or any wiring.
At this point I am not yet going to submit ticket to them suggesting it is a faulty unit, but I did discover this in the manual….

Not sure how this reads as it could be interpreted either way but it *could* read that a 12v ignition live (but without the engine running) e.g. just turning on ignition but not starting the van may not be enough for the Ecoflow to detect a charge coming in.
Or it could mean having the Ecoflow connected to the ignition live before starting the van may mean the van battery voltage, due to the Ecoflow load, is not sufficient to crank the engine.
So, maybe I need to install a switch somewhere in the driver seat vicinity so that I can have the ignition live to the Ecoflow switched off until the van is running and then I can switch it on.
Isn’t this what a DC-DC charger does automatically by detecting the increased voltage from the alternator? Starting to think I should have just got a leisure battery install - these solar generator battery banks seem more geared up to solar charging (hence the name I suppose) than charging from the van battery
