This is the truck I tested at the Volvo Truck center. Although it's not me driving in the video, it's still the same truck! Remember to like and subscribe if you'd like more videos like this.
Ah, but here in Sweden 24m is quite normal. So is 25,25 meters. But if you want to see something really cool you should see the radtrains my company drives on a daily basis. Just search for RPG Roadtrain going on tour.
Having used Google Translate to try to interpret your message I think you mean that you would like to know more about the FH540 and the FH750? If so I recommend the official homepage, www.volvotrucks.com, as I don't have any extra info.
