[Diesel + Trailer] Crubla Re Re tests

This version is a public test of the Kenworth T680 Next Gen. It is just the first playable version, so it may contain bugs, unfinished details, and behaviors that we are still adjusting. The painting areas are located at the back of the spawn area and in front of the refrigeration work. This update does not represent the final version of the Next Gen. We will continue to fix, optimize, and improve the truck, the driving, cameras, interiors, and visual details. Thank you for your patience and for continuing to support the development of Crubla. ❤️
