Autocar 8x6 tractor model?

Does anyone know the model and/or use for these Autocar tractors? Crismon doesn't seem to mention them.
The first pic is of two that sold out of APG years ago on GL, and the second is a pic I found somewhere online.

I know what you mean. They are kind of M911-esque with the sheer size and the drop axle, but I like the hood and cab lines better. More traditional tractor. I was not able to go look at the two when they came up years ago, so I don't know anything about the engine nor transmission/transfer specs. And, I really have never been able to find anything about them.

Reminds me of the Killer truck in the movie “Duel” with Dennis Weaver.
