-1 We have World OF Trucks which gives the ability for friends to get the same trailers we also have Virtual Speditor which gives us trailers of our choice. But +1 due to the fact it'll make it easier to distinguish convoy participants and also it gives a higher chance of getting the same trailer. So I am in the middle with this suggestion

-1 No need for this server. There are already enough servers. Just some servers have different options such as Eu1 which has a speed limiter etc etc Eu3 is the exact same as EU2 just with cars disabled.

First try to restart using alt f4 or quitting the game. Then try re linking your ets through the launcher. If it does not work after the re linking of the directory try re downloading truckersmp as a whole there could be a corrupt file in your download.

Yeh you can paint trailers like you have done and use them within the game. Just don't change the trailer itself so the colour is fine but don't change the trailer contents in anyway.

+1 Love this idea ! Very true would make it a lot more simpler and would love to see in game.
