I'm looking for some # on what it costs to maintain and operate a cab over diesel dump truck like a Fuso, UD, Isuzu etc. I have 2 but they are so new that I can't do more than project how long they will last and what will break when and how much it will cost to repair. So I don't have a comfort level that I am charging enough to cover the full maintenance/replacement costs. I'm guessing there is some documentation on this done by a reputable organization or by someone who has been using these rigs a lot longer than I have. Any guidance would be appreciated.
