Heavy Haul truck setup questions

This has got me way confused. Im looking to purchase a truck when i get back to the USA and reading this thread has stumped me. Over here in Australia we have all makes of trucks pulling doubles and triples with doubles weighing 140k+ and triples up around 180k running at 70mph and wanting more, running 18speed eatons opti cruise autos and 12sp autos without a problem averaging 5mpg which truck in the US will give the same.

 

Someone (not you mumbles) needs to get familiar with Google for heavens sake.......

did you ever hear any of us old timer talk about a "twin stick" transmission setup?
that is a 4,5 or 6 speed main trans with a 3 or 4 speed AUXILIARY trans and the aux is
shifted 2 or 3 times for every main trans shift.

you will notice that many drivers running twin sticks have a different knob on each stick
(to identify in the dark)

 

I am sorry. This cannot be true. I read a post from a 0-1 year trucker that said automatics are superior in every way and cheaper to maintain. He knew that because the three biggest Youtube truckers said so and they all had automatics.

 

You guys should try my 4.33's and 22.5 LP.

 

I've got a couple trucks with 4.33's but they are on 24.5 tall rubber. They will pull the world up a mountain but the fuel mileage sucks.
