    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 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.

    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?

    Our vehicle worked out safe on all accounts, but, the compliance plate on van axle group load capacity is lower than the GTM.
    Why would a manufacturer of a new van quote an axle load less than the GTM.
