I was half joking but half serious. I am no Cat hater by any means. On the contrary, I prefer Cat for most types of equipment. And I love Cat scrapers having spent some of my nicest work days on 627s and 637s. But in my (I admit kind of limited) experience on a Wabco, it was not as bad as most people seem to think they are. My experience was on a later one with a steering wheel, not one of Robert LeTourneau's atomic age electrical marvels. It was an open bowl machine, not a self loader. I understand, maybe if I had to earn a living on one of the toggle switch steering or the WW2 era steering clutch machines
I would feel differently. I grew up hearing my Dad and the other old timers say that the later Wabco self loaders could hog so much more dirt than the other makes, maybe that's why I have a fascination for them.
