I’ve weighed out the cost and I can not justify it. I also have a commuter car, so my truck is strictly used for towing and ice fishing. Gas all the way. If my trailers weighed more than 6-8000lbs, I would consider a diesel. The maintenance for long-term ownership and repair cost have kept me from owning one. If you trade your truck in every 2-4 years, read no further and buy a diesel, you’ll like it. If you plan on keeping it for 10-15 years, read on.
The biggest argument diesel owners use when comparing is that they last twice as long as gas engines. Yes, that’s true but you are NOT taking into consideration the maintenance cost, mile per mile. They also bring up the MPG you can save using a diesel, but once you weigh in average fuel cost and the drastic decline in MPG if you need to use winterized diesel, the point is negligible…the gas almost always wins $$ wise.
My father and two of my brothers own diesels and they are each very happy with them. It’s personal preference once you weigh out the positives and negatives.
