Okay, I looked trough the threats and found some are asking about the Tatras. Other said they could repair them!
So for me:
Looks like one is at the first map between stones and another ist at the second map in the Water. But I don't know.
I have no taskgiver like other and if I'm near the trucks there is also no message that I found a new truck.
So, what's about these two trucks? Is it buggy, or missed I something?
