Appears to function properly after the 0.33 update make sure you clear cache and make sure there are no remains of the previous version of this mod.
New Update has been released! Available on the Repository! https://www.beamng.com/resources/nascar-gavril-d-series-craftsman-race-truck.29604/
It does have configs packed into it. I'm unsure why they dont show up. They did in the previous update until now. I have no answer to why.
Thats the old D-Series mod by Matty D which was a full custom model and jbeam mod. I don't have the know-how to model custom bodies like that otherwise it would. However you may see that mod pop up in the future at some point
everytime i download it. it doesn't show up in the gavril d-series car thing. I can find it anywhere.
