Note from the Author(Cobrablue6):
The equipment tower was removed form the 6×4 chassis because we couldn’t find any examples of it in real life.
I made an addon mod for you that re-enables the towers on the 6xx chassis.
Put it above the main mod in your mod manager.
* You need the truck MAN TGX Euro 6 v2.0 by MADster (1.30.x)
