Question on the load of attachments

Hello ! I drive an Astra 2.0 diesel with 105 hp which has a trailer load of 1200 Kg or 1400 Kg at 10 % incl. I would now have the question if I can drive with a caravan with 1400 Kg to Italy via the Brenner motorway or to Venice. What does it look like with the Irschenberg ? Does my car manage this ?
