    My manual strongly reccomends not putting antifreeze in the grey tank as it is a corrosive and could attack the seal joints. Regards fresh water tank if the possibility of freezing is a worry when you are using it in winter then take bottled water with a refill often.

    the correct way to use safe, non toxic antifreeze is to drain the system fully first, including the boiler.
    then introduce the antifreeze and draw through all water lines until it comes out the hot and cold taps....including the shower and toilet if fed from the main tank.
    if the toilet has its own tank then dose that and draw through to the toilet bowl.
    then turn off the pump and leave the taps open.

    it isnt toxic but does have a slight taste so will need draining (you can reuse it next year) and flushing through before recommissioning the water system after winter.

    Your fresh tank is inside, you don't need antifreeze!

    If you are standing the van up for winter, just drain it down!

    even a water tank inside the van will eventually freeze no matter how much insulation it has unless the tank is heated. we don't drain down until a bottle of water stood in the sink freezes then I know that in a day or three the tank is at risk
