    A big help. But does a weight distribution hitch change these figures and can I keep this as an app?

      Hi Greg, thanks for the question. No, a weight distribution hitch doesn’t affect these numbers – all a WDH does is transfer weight from the rear axle of the tow vehicle to the front axle ‘distributing’ the weight more evenly across the vehicle. Check out a video here describing the process – https://www.youtube.com/watch?v=3-PyN0EY3Ww

      Hi Peter, have you got the ATM weight entered correctly? Tare weight is what your van weighs empty. ATM is what it weighs if it’s full.

    Hi Brendan, I am confused by your details included in the latest RAC magazine re vehicle weights. Page 30 refers to a Toyota Fortuna and the relevant GCM and GVM values.
    I don’t think your maths are correct, and would appreciate your comments.
    Regards

    Hi I am confused also as I am under weight on all sides but over on the Gvm!
    I changed the figures around cause I am confused by the tare and kerb weight as the caravan has a tare and agg weight and as I understand the tare is the caravan and the agg is the loaded caravan?

      Hi Jos, we specifically don’t ask for tare weight, so enter the aggregate weight. You can still be over GVM (which is a limit on the combined mass of your cara and caravan), even if you are under weight in the car, and under weight in the caravan.

      Yes, negative weights are good.
