Audi 80 & Wilk CI Sport

Hello! I’m new here in the forum and I have a question for you: We bought an Audi 80 B4 (Automatic) 2.0E and a mini-car last year: a Wilk CI Sport 320 (BJ 1981) . We want to go on holiday next month, about 700 km away from us. I mean, we should get an anticle grouping, because my friend also likes to drive a little faster with WW … for the purpose of 100er approval! The caravan got the TÜV badge just before the purchase last year without any problems I’ve already tried to find out what kind of 100 registration you need, but somehow don’t get smart about it. Can any of you help me? So I assume that we certainly need an Antischlinger coupling for the 100 registration – but doesn’t it matter what kind of coupling? And how do you charge the WW best? Do I see this right, that you can charge relatively little on our train? We don’t need an awning, so the weight falls away. Also no gas bottle, because we live at the holiday resort privately and there everything runs over electricity. So comes in only our luggage, 2 folding chairs, 1 folding table and a few cold batteries in fridge, so that it is cold when we arrive 😉 Please forgive, if these questions have been asked a few times here, but my head is already swirling from the many search page results… 🙁 I thank you already for your answers!
