Years ago I did a comparison between the costs of a diesel and the costs of gas engine for RV towing. The diesel is more costly to maintain and costs more up front. Diesel fuel is also more expensive. One the other hand, the diesel gets better mileage and will usually last longer than a gas engine. I found the break-even point of the additional cost of the diesel at about 70,000 miles at the time of the study. In the end, it's more a matter of personal preference. I love my diesel for towing my 14,000 lb fifth wheel.
I have no doubt that owning a 6.0 diesel costs more up front and is more costly to maintain. It was the second worst diesel ever put into an American truck; ever! If you would have bought a Dmax or a Cummins your outcome would have been different. Mine is. :)
