Hello everyone, since December I have the new Atego 816 = 7.5 t On Monday I pick up a trailer, own weight 840 kg. According to papers I can attach to the rear up to 3.5 t unbraked ABEEER: since I have a ball head coupling, is further down in the papers something with 2.7 t. Does there have experience how much I can actually attach now? 2nd thing that would be there= have heard of this modules, which every driver needs from 3.5 t until September 2014.. What do you have to do, what does it cost etc… A good link would be so nice as a hint About useful answers I would be happy and thank you first. Greeting, Frank
