Thank you for your reply. I haven't tried Freightliner but that is a great idea as they imported these trucks. I am mostly looking for oil/fuel filters, fan belts and hoses. This is not actually a semi, but rather like an extra large pick up. the 11 refers to the tons it is rated to carry and the 16 its horsepower (multiply it times 10). I will call the local Freightliner dealer.
