Friend of my father had some late "70's models with non turbo Thermodynes.Many old timers would not buy turbo engines as they didn't see the need.More to maintain and more parts to replace.

Overnite had a ton of MB607's up into late ,70's models also

That is true, and some would stick with gas engines only also! There was a guy near me who had a bunch of 6 wheelers, ALL gas into the late "90's at least!
