I don't have a C8AX parts list to confirm this, but my understanding is that the C8AX is more or less the same set of parts as the C8A Heavy Utility series from the ground up to the top of the frame rails with a C15A cab and a (probably) unique cargo box. So, if the C8AX is actually a 15 cwt, wrongly named, does that make all Heavy Utilities 15 cwt as well since they are the same structural parts and drivertrain?
