I have a bit of a thing about referring to the advice as rule - Its not a rule its only guidance. Giving calling it a rule tends reinforce the idea it has some legal impact It doesn't have any..... rant overWhen it comes to the 85% rule should I be including the driver or not ?
The way the guidance figure is calculated is full of illogical values, which do not take into account the vehicles actuall towing specifications which is why I don't like to recommend it fully.
Establish the cars maximum permitted trailer weight from its specifications (GTW -GVW) and bearing in mind its a caravan and that represents a significantly more difficult load for the car to manage, and that when towing a caravan the car is more likely to be well filled with people and luggage so it makes sense to keep the trailer weight as small as possible.
The most important weight limits (for which you can be prosecuted) is exceeding any of the limits displayed on your cars data plate.
As for nose load, the limit is usually set by the cars limit for the ball hitch. And whilst it is generally better to go greater, going beyond what you need to keep the out fit stable has no real advantage.
