Sterling uses vendors like Eaton or Allison for their transmissions and other drive line components. I would be surprised to hear they are having some kind of on-going problems that other makers using these vendors are not. As far as "weird glitches", trucks will have problems. I don't care what make it is, class 7 or 8, you will have some problems somewhere along the way. It's the nature of the mechanical beast. Most of the time, when I go by any service facility they are working on trucks. KW, Pete, whatever. I think it's a bit premature, at this point, to assume that Hino's relationship with Toyota will assure an owner of some better level of dependability.
While picking up freight in Tucson recently, I was having a conversation with a Hino owner about our trucks. I asked him about his fuel mileage. Now, if I'm asked, my reply is 10 to 10.5. A simple answer to a simple question. His response was to first pause, then go off on some kind of story that never got to a number because he had to go put his truck in the dock. I was only left to assume that the number would not have been impressive.
