Not sure that this is 100% correct bit I'm sure someone will correct me.
There are a few wieghts you need to be aware of.
1)The kerb weight is used to measure against the caravan MTPLM to see where you are with the 85% "Guideline".
2)The MTPLM as you probably know is the 'Maximum' wieght the caravan can ever be including all your gear and this is weight is stamped on plate located on the caravan.
3)The Gross weight of the car is the 'Maximum' weight the car can ever be including passingers and luggage etc.
4)The Nose weight is the wieght the hitch of the caravan can be when attached to the car. (Can be measured using a set of bathroom scalles and and lump of wood)
4)The Train weight is the 'Maximum' weight the complete car and caravan can be including all people, luggage, gear, etc. This can be found on the VIN plate of the car and must not be exceeded.
The train weight is probably one of the most important and most forgotten of all the weights. Example ()- my car can tow up to 1400Kg legally according to the manufacturer. The Gross wieght of the car is 1840Kg. The MTPLM of the caravan is 1300Kg.
Gross weight of car + MTPLM of caravan = 1840+1300 =3140Kg
The Train weight stamped on the VIN plate of my car is 3040kg. So as you can see if I go to the manufacturers max weight of car and caravan I will exceeed the Train weight and thus break the law.
In my example it is only 100Kg over but in other example I have seen it a lot higher.
Sorry for waffling on but it can be a complicated issue and I hope my long winded explanation makes sense.
Ps I know it is on a single axel but I have the Adria Altea 542DK which is a 6 beth and it is fab for me and my 2 boys.
