Drum brakes are quite widespread here, and so are manual transmission too, yet AMTs are taking much of its market share on vocational applications, as long as a PTO is not needed. Otherwise the best option for vocational trucks is a real automatic. I don't remember seeing many AMTs with a PTO.

An Allison automatic behind a Cummins engine is still the most common combination in the USA for Class 5 - 7. For the Class 8's Freightliner / Mercedes added a PTO to their AMT last year.
