Though Volvo is a Swedish company, Volvo in latin (where the company got the name from) means "roll". So if you were to put it in the repository I would suggest Voluto (meaning roll as a noun in Latin). VNL is Volvo North America Long Hood. So maybe put VUE (Voluto United States Extended Hood) and I assume 780 means how large the cabin is, so I guess any number combo fits. Voluto VUE [insert numbers here] Just a suggestion ♂️
I think you'll have to ask one of the developers who oversees the repository, or maybe @SergentFido . They'd probably know.
Well, I don't want to clutter up the thread with useless naming posts, but according to the BeamNG naming scheme, Volvo is called Jargl, so if you would want to keep with the "rules"... then you know what to do
