Hello, we would like to buy a van for our show technology operation and have a Mercedes Vito with truck registration in mind. The weight variant of the vehicle is: Weight variant 2, 77 t (1, 47/1, 47) Now also trailers should be pulled with this vehicle: 1. Small trailer with a maximum of 750 kg 2. Large trailer with a maximum of 2,000 kg Can these combinations be operated without a tachograph? Is it possible to avoid Sunday driving bans because of our industry (according to Wikipedia flowing transition from the show show industry)? If the above combinations are not possible, is it possible to load the Vito or small trailer? There are practically only 20 kg too much (2.77 t + 0.75 t = 3.52 t) Thanks for the answers.
