I will thank you Freeatlast.
Assume the distance between the wheel hubs is
1000 mm and in balance, the centre of mass is 500
mm, directly between the wheels. This will be our
datum, so in balance it will equal zero.So, we can now work out the moments:-
It can be seen that by moving the total mass of the
caravan forwards by 31.25 mm, the loading on the
front axle increases by 50 Kg and on the rear
reduces by 50 Kg. Moving the total mass of the
caravan forward by 62.5 mm will increase the load
on the front axle to 900Kg and reduce the rear to
700Kg.
Now, in practice, we can’t move the total mass of
the caravan forward, what we can move is the
items we store in the caravan.
Then again that may be wrong as well.

And the point of this is?
I think you have misunderstood what this is telling you. This is talking about changing the CofG by moving the whole weight of the caravan forward.
Firstly the distance between the CofG and the motor mover on a single axle will be very small to start with. However, in comparison the distance from the motor mover to the hitch is very large in comparison, thus there will be only a very small extra loading from the motor mover.
With a twin axle with 2 motor movers one will balance out the other pretty well so there will be an even smaller extra loading on the hitch.
So, decided last weekend to look for a BMW x5, then today, Kia Sedona went in for her MOT today, Passed with no advisories.
4 weeks ago I was happy to get rid of her but towed the caravan and how brilliant she was and to add to my sadness she passes her MOT, bloody nose weight!!!
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
