-Reworked the mesh one last time. (shape stayed exactly the same)
(added lots of detail like the opening mechaning on the rear and front, switches are now semi-3d aswell)
-Rework of the UV unwrap.
-Removed AO from wheels.
-Overhauled textures completely.

and...

-It took me 6 fucking hours (!) to make the normal and occlusion texture for the canvas cover.
(everything was hand drawn, i even went so far to generate math functions for parabulas to make the canvas fall smooth between the supports, usually theres tools for this but i like working with my hands tied behind my back...
i should get photoshop for this since it was really tedious making this texture work).

last but not least the usual stuff:
-Added guardrails below dampers.
-Added normals to backside of the dampers.
-Added platforms for workers to stand on.
