After the paint had dried, I could take care of the stickers. That was quite a fumbling until the stickers sat correct and no bubbles were present - my respect to all advertising technicians who do this with much larger films. Good thing the stickers from van den Hooven are so stable - they had to suffer a lot. What's missing is the sticker for the marquee at the top of the cab. I accidentally ordered a wrong sticker that is not translucent.

Now I could install the speakers - I'm using Pioneer TS-G1022i 2-way speakers in conjunction with a subwoofer, which will be installed in the bottom of the cab. The LED lighting is now installed. Additionally, I have glued aluminium foil at the sides for better illumination of the marquee at the sides.

Finally, I 've built the monitor apart to paint the silver frame casing with black spray paint. Thus, later the monitor casing doesn't attract attention behind the Plexiglas panel.
