Unlike most vehicles the m939 trucks are geared very low. I personally try to drive around 60mph on the highway. Any slower then I am holding up traffic. Any large vehicle traveling on the highway that cannot maintain 60mph should have flashing amber warning lights. At 60mph the rpms are around...

I see the cruise control as a safety issue. It's your truck you can do what you want with it.

You are correct. It just so happens that the m939 trucks are large but nothing close to modern.

Take it as you wish but I think installing cruise control in one of these trucks is plain stupidity. You want to drive it you need to pay attention behind the wheel and not let some gadget drive for you.
