Hey Thud....once a trash hauller...always a trash hauller! Yep...two tours in Vietnam, Republic of, flying 47's....and two tours teaching in them at the other CFS....one civvie tour flying them in Italy in Libyan colours.....but that is a another story.
Cockpit height about the same in the big truck as in the Chinook.....and the same overall length....105 feet. Chinook at max auw weighs 30% of the truck....burns 150 times the fuel of the big truck for the same distance and does the trip in 50% of the time. Truck stops quicker....accelerates slower....turns sharper....but will never be able to dissassemble itself nearly as completely or as quickly as can a Chinook.
