The vehicles can do a lot, but not everything. Everyone decides how to use it :-)

uh why is the container clipping trough the back

этот МАЗ 516 способен возить контейнер на шведском полуприцепе MAFI с 2 манипуляторами со скоростью 80 км/ч , на стандартном полуприцепе он был способен возить до 10 тон максимум. если не затруднит автора сделать этот полуприцеп буду признателен.

It's a great idea, and it's a very useful mod at the start of the game, when trucks are limited and can't carry large containers. Thank you so much

In addition, I really like the principle where the loaded truck goes slower than empty.

@ tajana_g: If weight in relation to speed play a role again in the game, I will change the vehicle values a little. Now I imagine an average value: empty weight approx. 60 km / h and very heavily loaded approx. 10 km / h.

I understand this idea, but wouldn't that truck be able to reach higher speeds on a flat road?
And drastically drop to crawl on an incline?

Very sadly this function was taken from the game. The very first version of it had it. If roads were steap vehicles could not reach topspeed. It forced you to built roads more realistic but I guess some kiddies complained that their trucks didn't reach 90kmh on an 50%+ incline :(
