I am also really curious what kind of truck he is driving.

It’s... very empty
Zil-Caterpillar prototype from early 1990s, when the manufacturer from Moscow tried to make something time-relevant and American-looking in collaboration with
Caterpillar and
PACCAR.
The seats look too short for long comfortable driving

.
Nothing of these prototypes were put into real production, and one of few reasons they aren’t forgotten is...
Hard Truck 2, where the cutest of these trucks (named
Zil-5423) was present.
(of course, the
ETS mod with it also exists

)

Also, they had a truck racing team in 1993.

P.S.
I see
Zil liked experimenting with off-road chassis.

I like the size of their wheels

.
Anyway,
Zil was literally shot in the head in early 1970s. They created a completely new truck for some other factory (that’s how
KamAZ was born)... and returned to make the obsolete vehicles at home.
