Permissible total weight in trailer operation.

Hello Forengemeinde, I would like to buy a trailer for my BMW 220i aut. The caravan that we are very interested in has 1300 kg maximum permissible weight. Model Eriba Touring. Since I have the driving licence class b, I can not exceed 3500 kg. In my vehicle papers from the BMW it is now written: line f1/f2 2130 kg And in line 22 F.1/F.2: +75 B. ANNEXES*7.2/8.2: +110 B. ANNEXESETRIEB WW.AHK LT. EGTG SOMMER AND WINTER SERVICE ONLY ON GUB OR SCHMIEDE-LM RAD DATUM TO EMISSIO NSKLASSE: 29.03.2016* What’s the bill then? 2130 plus 75 are 2205 Plus trailers 1300 Are 3505 kg Says, do I understand correctly that I and my wife have to make an extra driver’s license because of 5 kg? I can’t believe it and wanted to ask again if I understand this wrongly. Have you ever had a trailer charged ex factory?
