Bill, I think it might be the Actros over there, just by looking at the specs and pics. I never actually looked at the name plate when one drove by me. Actros is their most heavy duty one with up to 40 tons, (88,000 lbs).
Of course we would have to go for the special edition "Black Edition", as per their page the strongest truck V8 in Europe, 15.9 l, 612 HP, 2060 lbf torque (if I converted correctly) black on black, nice body moldings.....
Now thats a machine for chevy57 to get started at.
