This is for vehicles such as the Gavril D-series have have more than 1 version of the same vehicles that are not like the Ibishu Pessimas. Now there could be a few different ways of implementing this but I thought this would be a good start.
I'm pretty sure BeamNG's current UI would make implementing this very difficult, and selecting configs would become needlessly complicated.
i usually do that with mods avaiable on the forums but i like to make the separated vehicles for a easy use
If they could update the 800, Sunburst, and K-series to 2020, with a new front end and new gauges, that would be awesome, I think
