You can find the UV templates in the game's installation folder > content > vehicles, inside the ZIP of every vehicle that support skins
Please make sure you are looking at the correct folder. Not the Documents/BeamNG.drive folder, but the folder where the game is installed (if you use Steam, usually is Steam/Steamapps/Common/BeamNG.drive)
