Re: Massive Understeer With Default DAF XF105
Is it possible that the middle axle suspension is too stiff? Maybe the tag suspension could be given some more stiffness and/or even lower more than it does to lift the rear a bit more.
Re: Massive Understeer With Default DAF XF105
I must say i haven't looked into this issue myself because i have barely noticed it in game since i don't drive the affected trucks. So there's that.
If these things were a priority for me i would have looked deeper and had better suggestions on how to fix it.

So have to move the 5th wheel just above the middle axle, right? I will install blender and i will modify it. Is it difficult? Never used Blender.
Btw in real life is the 5th wheel above the middle axle? Judging some shots is between
the tag and middle axle.
Thank you for the help.

Import, move dummy, export. You don't have to move the visual wheel. Just move the dummy.
But do it in mesh edit mode. Don't move it in object mode.

Didn't have enough time to modify the truck but i found something interesting (at least for me, maybe for you it's obvious ahaha): the problem is seems to be related to the chassis flexibility, i mean you feel the problem ONLY if you use the engine over 50% of performance. Look the turbo gauge, and feel the sensations: if you only use the "green" area (for the Scania) you don't have any problem, but if you push the engine to the limit it seems to "fly". Maybe there's something related to the chassis as well.

SCANIA wheelie!
Re: Massive Understeer With Default DAF XF105
exactly. Well at least it happens even in real life. I think i will swap driving a classic 4x2 truck. The 6x4 actually it's almost undriveable, at least for me.
Edit anyway the solution is, like you wrote, to move the 5th wheel forward. Waiting for an official fix at this point, or at least a customizable regulation.

Re: Massive Understeer With Default DAF XF105
the problem i find with this is with all trucks not just the daf xf105. The under-steer on all trucks for heavier loads (IE: 40tons +) is so bad that most trucks end up just driving straight when i hit the gas and turn at same time. I just end up going straight no turning unless i let off the gas when i make a turn. Even then it is horrible. Until i get to highway speeds like 60km/h or greater.
I currently use the Kenworth T800 with 6x4 chassis as my main truck. And to see the under-steer so bad at low speeds is off putting. Because i know this truck in real life is a serious power house for pulling heavy loads (CAT 3 rated which is about 150tons). I understand some under-steer with heavy loads is to be expected but so bad that the truck fails to turn at all at lower speeds (50km/h or less) is completely unrealistic considering it happens will every single truck i try it with, heavy haulage chassis or not does not seem to matter. Tag Lift Dual Steer chassis helps a bit but not much.

Re: Massive Understeer With Default DAF XF105
The problem is for all 6x4 trucks when there are greater loads to 18 tons
