Id say that's a good price on that low of mileage (or at least it would be in my area). The DT is an awesome engine too. I'm a 5.9 as well, but Cummins. I've got insurance through Progressive COMMERCIAL. Its not the same as the Progressive Auto. The auto division denied me, and i called right back to the other division, and no problem.. I insured as a bus for a personal use, I didn't even try dealing with the RV end of it.
