Congratulations!
We're just looking so very confused.
The problem is we only have a 1.4l Astra.
The caravan we have seen is M.A.W 1200kg.
Figures I can see on the registration certificate are:
Max Permissible mass: 1735kg
Mass in service: 1240kg
Then there is another section.
Technical permissible maximum towable mass of the trailer:
Braked: 1000kg
Unbraked: 615kg
