I've never really been a CAT fan myself (Even though I live here in CAT country). I'll take a Cummins or IH powerplant anyday over a CAT. I drove Volvo's for a while. Their engines were smooth and quiet. They didn't have alot of low end, but boy would they run out on the top! As far as road trucks go, I'm going to put the CAT in the same category as Kenworths for now, no thank you. (Sorry HevyHauler)
