Anybody else????

Yeah they do. Even our skids take def.

And yeah I don’t know anyone running those cat X international trucks.

 

I am not talking about the international truck they called a cat. lol
I am talking about the class 8 trucks they ran on the haul road for several years testing the engines, they hauled concrete barriers back and forth, also went down to valdez when weather was bad up north, the engines reportedly were scrapped.
I know cummins had a nice shiny t800 up here for a while testing a cummins, it ran shy of 50 ,000 miles and was cut up for scrap, hard to belive they would do that to a nice heavy spec truck.
