Progress update
I glued everything in few main sub assemblies, then tried something new. I wanted to replicate color chipping on the wooden cargo bed planking but the problem is that there is no wood grain effect on them. For some time I was thinking how to overcome this problem. Normally, when replicating wood, I sand of plastic with coarse sanding paper and it works fine for me. But that is hard to do on model, since there are some unapproachable places and details which could be damaged. So, I masked of what should be metal on model and applied undiluted acrylic paint with shortened stiff brush. This one.

and keep on pulling brush in the direction of wood grain as it drys. Result is not that visible before applying wash.

But, after wash

And finally with paint

It looks ok.
So, Blitz before base color

And after, which is where I am now.

Probably a campaign too far for me with my current schedule, but let us see...
