Karl,
Try and follow this -----
Consolidated Freightway's contracted White Motor Co, in the late 40's
early fifties, to build a cabover semi, which they designed.
The contract with White ran out in the mid 70's, and Freightliner went
off on their own.
MB purchase Freightliner about 5-6 years ago.
Volvo purchased GMC class 8 vehicles in the  80's, and then they gobbled
up White Motor Co. a couple of years later.
Now Volvo has just purchased Mack, the last bastion of durability, in
the truck world.
Sad.:>(
A guy needs a scorecard just to keep up!!

Later,
