Waduh waduh luar biasa Truk dan supirnya mantap2 benar bos super super hebat bis.Woww...it reminds of time in the middle of Borneo Indonesia drove Volvo trucks with heavy timbers to the Mahakam river....very hard n tuft job then.More power needed but awesome driving!! I love watching my fellow drivers around the world! Brothers all we are!!!The danger there if the truck brake will malfunction, the log tie accidentally loose and the truck tires will explode then that's it. the workers received reasonable salary plus overtime but very risky, I remember my younger days my father works this type of jobs and many have died due to truck slide in the mad. Four wheel drive plus tire spike necessary for the truck.
