I currently drive a 2004 F350 6.0PSD auto CC 4X4. I was commuting 50 miles a day and getting 14-17 mpg on Connecticut's highways ( 85MPH- crawl)very happy with the truck. My new job takes me 1.9 miles door to door. What is this going to do to my truck, even if I take the long way (6 miles) it still won't get to opperating temp.Should I be looking at a gas truck? I don't tow or haul anything I just like a CC Super Duty, I am looking at a 2006 King Ranch F250 CC with the 5.4L V8 4X4 3.73LTD slip. AT 3.00+ a gal for diesel and unleaded not to far behind is this a mistake or a wize move? Any input would be great.
