i want to be a road train driver

http://en.wikipedia.org/wiki/Road_train

"U.S.A.
In the United States, trucks on public roads are limited to two trailers (two 28 ft (8.5 m) + a dolly to connect; the limit is 63 ft (19.2 m) end to end). Some states allow three trailers, although triples are usually restricted to less populous states such as Idaho, Oregon and Montana. Triples are used for long-distance less-than-truckload (LTL) freight hauling (in which case the trailers are shorter than a typical single-unit trailer) or resource hauling in the interior west (such as ore or aggregate). Triples are typically marked with "LONG LOAD" banners both front and rear. The term "road train" is not commonly used in the US."

What you are referring to is nothing more that pulling doubles or triples. You need the endorsement, training, and experience with a particular company that will get you enough seniority (or knowing the right people) to start training you for this. I don't have experience with this but I do know that it is a completely different monster. Talk to LTL carriers and those that have their own fully developed distribution systems.

 

Oh, this is what you are referring too...

"K represents the largest road trains operating in Australia, and therefore, the world. Called a "Powertrain" or a "Body and six", these machines operate at The Granites Gold Mine in the western Northern Territory, and are used inplace of 200t dump trucks, because of the distances involved on the haul run. A 600 hp 19 litre Cummins engine powers the prime mover, whilst a 400 hp Cummins engine is installed in the rear trailer of the B-double, driving through an automatic transmission, giving a total of 1000 hp. Weights of 460 t (1,000,000 lb) are achieved with ore loading in side-tipper bodies on a 100 km round trip. As these trucks operate on private property, they are not subject to governed weight and length rulings, but instead are utilised in the most efficient way possible."


That would be CRAZY!!!

 

here is one down side to driving road trains, while i was driving road trains carting copper ore another work mate and i finished for the day and sat down and had a few beers and a chat (as we did most days) he looked absolutly shagged and i said hard day mate, he said yep I had 22 flat tyres today. we had to change our own tyres so you can understand how bugged he was. i was so greatfull it was not me, the most flats i had in a day was 3 and that takes it out of you, cause the temps out there in central OZ get up to and over 45 degrees C (113F) with no shad and hardly any breeze.
