Experience with the new Vivaro Bi-Turbo?

Hello. I am thinking of getting the current Vivaro with Bi-Turbo engine (145 hp). We mainly need a large family car with plenty of space, but also as a towing vehicle for a caravan (1600 kg) plus holiday load it should be suitable. And exactly on the second point I wonder if it is not a little undermotorized for it. According to technical data it may pull up to 2to, but my other 1.6 L diesel (no Bi-Turbo and only allowed up to 1700 kg train weight) is a bit difficult. Does anyone have experience with the model in train operation? How are your other experiences with the model, especially in the private environment. The reviews on various other portals are very disappointing, especially in the area of the indicated mottled consumption values. But that wouldn’t be the most important point for me now. By chance someone knows if a model update is planned at Opel or Renault in the foreseeable future? With my luck next year a new model will come and then you won’t wait black. Would you please me to read one or another experience.
