I have a 300tdi 130HCPU and a Haulmark p1.1 750kg trailer and have a couple of questions.

From memory the centre of gravity of the trailer is approx 320mm forward of the trailer axle. If I were to carry the maximum load, how much weight should be forward of the axle as opposed to behind the axle? I've read that some trailers should have more at the front than the back but I couldn't find any real details on how to calculate the weight distribution. Is ball weight an issue with this combo and/or lunette ring/pintle hooks?


And


When connected to a Perentie the trailer sits horizontal as the pintle hook is located just beneath the rear door.

When connected to my 130 via a pintle hook adapter in a Hayman Reece tow hitch receiver it sits approx 120mm lower and the trailer now sits at an angle with the A frame pointing downwards slightly. Tyres on vehicle are 255/85 and trailer are 7.50r16. Curious how much this change in angle would affect the 'ball' weight and/or the weight distribution in the trailer. And if I change to 235/85's the front of the trailer will sit even lower so same question.

Below is a rudimentary picture to explain what I mean. Red illustrates the horizontal. Top is a Perentie/trailer combo. Bottom pic is using a standard tow hitch receiver. (Not to scale)
