I'll never go back to gas, but I sure miss the 7.3 engine. I've got one with the 6.0, fortunately after all the computer problems were rectified. I've driven Dodge, Chev, and Ford, gas and diesel. For reliability reasons, I'll stick with the Diesel engines, however, most of our driving is highway rather than tooling around the city. In the low speed start stop start environment, gas is a better option.
When I do my remounts...I'm seriously looking at a Hino.
