Hi
I have a 2019 Troll 540 which I am planning on towing through Switzerland with my BMW 435d (total wt <3.5t).

I have seen that the normal max. towing speed is 80kph BUT I have found info here* (all in German) that since Jan 2021 it is possible to tow at 100 kph on motorways if your caravan has type approval for 100kph. This exception is usually referred to as "Tempo 100".

The website helpfully shows examples of type approval documentation that you can use to prove you are legit to the local constabulary!

Now, my problem is, where can I obtain a copy of the Troll 540 Type Approval certificates?

I have looked through all my documentation without success so have written to both Hymer in Germany and Leisure First. Has anyone successfully obtained these documents before?

Some Italian colleagues have made this "Tempo 100" homologation. To obtain it, they went to ADAC o TUV centers in Germany, taking advantage of a period of vacation. They had to present a whole series of documents which, if I'm not mistaken, concerned the caravan, the tires, the braking system and even the car. I certainly know that all trains, cars and caravans are homologated, and I don't want to use the 100 if you have a different car. There are not many countries where it is possible to use the 100. Remember that even if you have the homologation in Italy, for example, it is not recognized and you have to go at 80 km / h.

Thanks for the reply.
One of the key statements in the website I shared in my first post is that for approval on Swiss motorways there is no need to visit the road traffic office. It translates as " Whether the trailer has a 100 km/h approval can be determined from the type approval. In order to be allowed to drive at 100 km/h, there is no need for a test at the road traffic office." The last part being the most important and that's why I am trying to obtain the TA documents.

I spoke with Leisure First today and they couldn't help so now hoping for something from Hymer...if/when they reply.

Looking like I'll be stuck with the 80kph limit. This is particularly frustrating when I consider that I can legally tow at 130kph in neighbouring France.

Yes. Good points.

Is the information required not shown in the Certificate of Compliance which is supposed to be supplied to all first owners as part of the Type Approval process. It contains a mass of detail about the van and is a sort of document of official record. Sadly, although it's been a requirement for more than a decade, UK caravan dealerships (and car dealers too) are only just waking up to its importance and there's very low awareness amongst actual owners. I believe a copy should be available from the manufacturer, though it may cost.

I agree entirely. That's exactly what I am after.
As I mentioned above, I've written to Hymer and await their reply.
