Good day together, we’re just thinking about getting such a ride. But background is that we want to/have to pull a 3.5 ton trailer with it, according to a seller at a dealer, the “this only works up to 2,8 to. ” , is that really true ? Prerequisite further would be that car needs a car registration so that we can drive on Sundays too. Does someone have an info for me, thank you so much
