    Running an inverter producing 240V in a moving vehicle of any type becomes a safety risk in an accident.

    Cheers. I might be better investigating 12V a/c if such things exist for bigger vehicle/RV spaces! Back to Google.

    EDIT
    Just found this on the Dometic site - asking for more info, as appears to apply to a specific range of a/c only
    Using the air conditioner while driving?

    To get the best use from an RV air conditioner while you’re on the move, a DC kit can enable mobile operation from the 12V vehicle battery.

    Perhaps they don't use 240V electrics, instead running on 12V or similar. My Waeco fridge can be powered by 240V but its compressor is low voltage AC at around 17V IIRC. A 12V kit could be useful away from caravan parks if one has enough solar power.

    Why does the dust suppression vent need to be powered? In the link I posted above there was discussion about scupper vents. All that is needed is enough air to go in to ensure the pressure inside is higher than outside.

    It is all a matter of personal choice. I'm not satisfied with scupper vents and want a POSITIVE AIR SYSTEM that I can control in dusty situations. I've used caravans in various guises for much of my life, so been there done that.
