Hello, I am new here and my name is Guido. Now I have a question. I have a Vito 115 CDI, Bj.2007, zGG 2,8t, 2 seats in front, a closed partition wall, no windows, only Sortimo cabinets, and it is allowed as a truck!! I am independent, and that with maintenance,repair,and assembly of waste water pumps and submersible pumps in all of NRW. So it always smells like something in the car. So now my question I have to keep a travel book in order to make it clear to the tax office that I have the Do not drive privately?? I also have no rides from home to the company because it is at my home. I hope for your help. Greetings Guido
