Find your trailer mod for Ets2 1.26.x game version
The game has very noticeable 3D-animated indicators, for the trailer to haul,
respective for the lot where the delivery has to made, finally.
This mods makes the wobbling symbols in the hight invisible. The bright frame on the ground is reduced to barely visible sidebars.
The front edges of that frame are removed also, only those in the back are remaining, to still have
an indicator when the game will accept a properly parked trailer
Be warned, you may not want to use this mod until you are experienced enough to find all these spots without much looking.
Especially on night or when it rains.
And there might be problems if you use map mods which have made changes to prefabs or sole objects using this stuff,
especially if the hight of such objects is changed. If spots are invisible due to such a situation,
try your best by watching the hint on the navigation assistant (GPS).
