Towing with 2.8 Landcruiser?

We are considering buying a 2016 Landcruiser to tow our 2000kg caravan however the nose weight on the Buccaneer can be up to 150kg as it has the E&P system fitted.  The average nose weight on our caravan is 140kg however the maximum vertical (nose weight) load on the towball on the Landcruiser is 120kg so we have a concern.  Is any one towing with the 2.8l Landcruiser as we would like some feedback before committing ourselves.
