Tachograph Tranporter

Hello, I have read a lot of different things on the internet about the tachograph recording or the running of a day control sheet or the running of a travel book. After I am currently doing in the driving school FS C CE I could also take note of contradictory statements there. Who can answer following question: 1. Transporter Fiat Ducato z. GG 3250 kg. Craftsman with own tool that I need to work daily. At the same time I have as a craftsman goods on board For example, a new washbasin. The vehicle has a trailer coupling. Do I need a tachograph here? Or do I have to keep a day check sheet? Or do I have to keep a travel book? How about these 50 km, I really don’t understand that yet. 2. Same vehicle as above under 1. Fiat Ducato, z GG. 3250 kg and trailer, e.g. GG. 2860 kg. Craftsmen with own tools and goods, same requirements we under 1. Do I need here a tachograph ? Or do I have to keep a day control sheet ? Or do I have to keep a journey book ? How about these 50 km, I really don’t understand that yet . It would be special to clarify if yes, is now a day control sheet to keep or a journey book . Is probably a difference . 3. At the same time I want to use the same vehicles as in paragraphs 1 and 2 now over the winter as a courier service vehicle . So the transporter or optionally transporter and trailer . This is a tachograph ? Or do I have to keep a day check sheet ? Or do I have to keep a travel book ? What about these 50 km, I really don’t understand yet . Special: Do I need this fitness test or a transport permit here without or even with a trailer . And what is the difference between a transport permit issued by the Landratsamt or by the EU . Who can answer these questions correctly is definitely an angel . My driving school could m I am a correct man and I want to avoid handcuffs in a check. As it looks like, transporter drivers and truck drivers are treated as criminals anyway. Last question: load securing: drilling machines, drill hammers. If all these machines have to be secured by clamping belts, or if a rutsc It is completely unclear whether new mountings have to be installed here every time by cordless screwdriver and the machines (every day we have other machines on board) have to be secured separately. To answer these questions I am happy about the news of the angel. Merry Christmas. I am curious about the news. WS Schatzi 1 000
