Golf V and caravan? Ask for your help!

Hello dear forum community, I’m new here, and with new caravan…. so also with many new questions. Since the first tour is almost imminent, I now come to the topic “loads”: so axle load, support load, etc… and then the question arose to me, whether it could become “eng” and I have to take special care somewhere. Tractor is a Golf 5 TDI 1.9l with 140hp to be pulled a WoWa “Thrun-Eicker” world boomler Here are some data from the registration certificates of the B vehicles: GOLF 5 TDI 140PS 1.9 l F1: technically permissible maximum mass in kg 1910 7.1: technically permissible maximum axle load per axle group in kg 1080 G: mass of the vehicle in operation 1391 Q1: technically permissible towing load in kg 1400 over 8% incline, below which up to 1700 13: support load in kg —— ((a)!!!)) caravan THRUN-EICKER Weltbummler 520 EZ 1973 F1: technically permissible maximum mass in kg 1200 7.1: technically permissible maximum axle load per axle group in kg 1200 The following considerations are still valid: Uncertain: 1. How heavy can the overall crew be at the end, where in the driving licence is this? 2.) Can I calculate the rear axle load of the vehicle somehow? Or does it only help to weigh? 3.) No support load is given for the towing vehicle; is the good? or bad? Speaking of weighing… the police will check the following works for my information when checking: the Wohnwagen — certainly quite simply: only the ready to drive Where to put on a large scale scale the drawbar load of the WW — here I need please a tip from you car total weight — I can still get that. But is this just the car or the overall car? Rear axle load with coupled trailer — Only with the rear axle on the scale, front axle and where down from the scale? Can I pull the woWa with the car? What to consider? THANK YOU for your helpful tips and answers… Gruss Daniel
