Cost of maintenance by spec and year/mileage
I am looking into buying a second truck. I Just finished a year in Mammoth. I went with the pre-egr philosophy of a simple aerodynamic truck. Truck had a recent in-frame and transmission overhaul and 1.3 million on it. Average mpg is 6.7 and maintenance cost including a full set of tires and more was, rhetorically 25 cpm. I can continue without going into California so that is not an issue. To some extent I can say I bought an old crappy truck and have been fixing it up. Another issue is I do not do much of my own maintenance because I have a family with three kids under 4yo to to quality time with. The goal is to build a fleet not to drive a truck. Operation: 47 states 53' reefer typically loaded to 70 gross and above. Currently profitable. I am aware that there is a point at which it is easier to get more profit increase with a first truck than by adding a second. This is not that question.
Going forward, is there a year in the newer direction when all this emissions crap starts to be well designed, where the fuel, reliability and maintenance costs start to improve? I am thinking along the lines of, at what point is it more cost effective to pay more up front for a newer broke-in truck with less deferred maintenance and better mpg? for those who have bought newer trucks, what experiences do you all have with newer models?
Is this a worthwhile discussion?
