Is the majority of the rear cargo area made of wood? I'm building the ICM kit and there is no wood grain texture on anything. It would seem to me that the floor and upper rails are wood. Is that correct?

After some searching, I found a Russian defence contractor who has specs for the 4320. Their url is http://www.rusarm.ru/exprod.htm and in case the link doesn't work, I'll quote "metal, with tailgate, removable bows and a canvas,side folded and central removable benches as well as additional side and front extension boards". Just like the American or Canadian utility trucks, then. Hope that cleared it up, and happy modelling.
