I haven't conducted a specific experiment to see if all truck have the same physics if used same trailer and same speeds and every other game setting, but volvo i have found to be very stable at high speeds like even 130kmh or 140kmh..towing a 24T trailer. As for heavy cargo's with the transmission i mentioned and if we don't use the 8x4 chassis which was designed for heavy cargo, on a 6x4 it handles pretty well too, be it paved or unpaved surfaces. Ever since in a update differential got added to all trucks, i found stability and physics to be improved too.. As coming to your last part of the question, which is most stable on the curves, now that relies on chassis,speed and the angle of curve, how you approach it and how much weight you got on the back. So the answer to that question is like infinite honestly because there are so many curves on the base map, everyone's driving style is different. So the answer you're looking for is ultimately in your hands. Drive all trucks through a tight curve with maximum trailer weight and push it as hard as you can. One which doesn't flip is your lucky winner. Good luck!

If we talk technically as per game physics then alot of things matter like trailer,trailer axle count,game play settings,truck axles,etc., and there are infinite answers to your question.. But from my personal experience, The new Volvo FH16 along with a 750HP engine and Allison 4500 R transmission , paired with a 6x4 chassis is an all rounder. Be it a light / moderate weight trailer or a heavy cargo one. This thing can handle it all without any issues. I have been using this configuration for well over 8 months. The transmission works wonders with that torque converter! In heavy cargo it picks up speed so good , i mean engine is already producing 750 horses and with a torque converter the time to pick up the speed reduces and works brilliantly.

The one i like and love isn't listed so i'll write it here. One Plus 7 Pro.

Bit late to the party here but thank you devs! Finally a step in the right direction and to a greater good.
