Mod support is a planned feature for Convoy. But as evidenced by the DLC requirements being lifted, it is not impossible for people to play with mods that don't match. You will likely have them streamed to you like it does if you're missing cargo DLC. I would guess so. Probably the host tells what mods are necessary.
Euro Truck Simulator 2 is an authentic depiction of this job, putting you in control of highly detailed vehicles. But SCS Software is using virtual reality to take things up a notch. Now you canEuro Truck Simulator is a European first - a truck simulation game in a European setting, with European long haulage trucks! Drive cargos from Rome to Berlin to Madrid to Prague - and many more cities - in realistic vehicles. Euro Truck Simulator is a faithful reproduction of driving trucks on the European road. the native multiplayer in the game is called convoi. once he joined you drive on the same map/world. you can pick up the same jobs so you will drive the same route. its not mandatory to do the same jobs but then you only do it for having simulated CB radio. .
