I am trying made a mod where you can buy an old or new truck from a dealer with an interior from modern trucks (From Scania S and Renault T 2021). The work is not easy, there are many lines of code to rewrite and from the screenshots you can see for yourself that not everything is still perfectly smooth (I promise that it will work in multiplayer).

For example, I took an old model of a DAF and IVECO trucks and rewrote the code and made it a Scania S interior (one V8, other default). You can yourself pay attention that not all the details are in their place, but outwardly the truck looks like a bug from a third person (inside the cabin there is a transparent interior, and just the very interior of the cabin sticks out from under the chassis).

And there are still some questions about the tuning of this modified truck, after any change in the truck (that is, tuning) the interior completely flies off and turns into stock.
