Unless you store your truck in a continuously heated garage, with your described driving, it is spending virtually all it's life with the engine never up to temperature.
Pre-emission or not, that is really hard on any diesel, and likely part of your lousy mileage. If you haven't already, it's probably a good idea to get UOA done, as this is Severe Duty usage in terms of engine oil.
Agreed - your story is a good example of a bad application for diesels. Living in Death Valley, perhaps an exception.... :laughing:
Rgds, D.
And that's what I've been trying to point out! I've contemplated buying another vehicle as a daily driver, but it's really not justifiable since I only drive a total of 7500 miles/year. I do plug it in in the winter, so that helps, but still, it rarely gets up to temp. I do follow sever service schedules, and my oil is usually changed at 4k miles or less, every 6 months.
