Not questioning the reliability aspect of this but damn those 6.2 F250 are gutless bastards. I had to use one to tow a 10K trailer to Arkansas from Grand Junction and over the passes I could barely do 60mph while almost redlined. Got 9mpg avg for the trip when I normally get 14mpg with the same load in my 6.7 350.The most reliable vehicle you can own now days is a 3/4 ton truck with a big bore gasser engine and drive/use it like a half ton truck 99% of the time. Modern diesels are far from reliable long term. All the modern emissions stuff is terrible for power train longevity, ask me how I found that one out the hard way. I'd go with a heavy half ton setup or a 3/.4 ton gasser setup all day long. Only get a modern diesel if you tow heavy loads on a weekly basis.
