Again, it's for moderation and space saving. TruckersMP sees around 7000 active players daily, through both games. If every single one could submit a paint job, it would be impossible to moderate. Limiting it to VTCs would give a more professional feel to TruckersMP as awhole but would also be a lot easier to moderate. As we didn't have to download all the vehicle mods that TruckersMP already has, some of which we can't all use, shows that not having to download them is a possibility, we don't download the 2 new cycling vehicles every month now do we? No, so it is possible.
