ProMods

Hello, I have one question before I download any new trucks to the game.
Are modded trucks replaces existing machines from the game or they are just added and can be bought like every normal truck?

Depends on a mod.

So maybe you can recommend me new trucks, vans and other machines which are ADDED to normal game, not replacing another car?

Po polsku tez można:
Polecisz mi w takim razie jakieś pojazdy które są po prostu dodane niczego nie podmieniając?

look here: https://forum.scssoft.com/viewforum.php?f=35

there you find the most popular Trucks which the modders also update if needed.
in the instructions they write always what it is, standalone or replacement.

Okay, thanks. Are there any limit of modded standalone trucks? I heard that dealerships have limited slots for cars - is this possible to add 10, 20 or more trucks and be possible to buy every one of them without replacing, deleting, moving?

I have personally added six standalone models to a single brand without any problems. Beyond that, I cannot say for sure. I haven't heard of this being a problem, but there might well be some upper limit.
