Australian outback truckers addressing enormous distances on tough and unsealed roadways must equip their rigs with special changes. They consist of a large bull-bar (roo-bar), a sheet of cable mesh for windscreen safety, special dust filters, additional long range gas tanks, quality tires, airconditioning and many different driving lights. Bulk goods are typically transported in path Trains, that may have around 3 trailers with a complete amount of over 31 metres.
