This truck is a very nice truck. I'm a bit disappointed in the fuel mileage after the last outing of 350 miles. Maybe the mileage is very good, but I was really hoping for better with a small block diesel. Straight highway, empty. I went approximately 50 miles for every speed increase to let the onboard computer AVG MPG settle (I have found after 3500 miles, it's very close +/- 1MPG. I was getting: approx 23-24MPG @ 55MPH, 21MPG @ 65MPH, 19MPG @ 75 MPH. The MPG dropped almost on the button 1 MPG for every 5 MPH faster. I topped of the tank to start and and retopped off the tank to verify. The onboard computer was accurate. I was hoping for 20-30% better out of a diesel. Weight ~empty: 7350 (on scales).
I originally bought this vehicle to tow a fifth wheel toy hauler which never materialized. I decided to keep the truck mainly because I enjoy driving it so much. Since itís diesel, it actually gets better mileage than an F-150 so it really didnít make a whole lot of sense downsizing. Iím really impressed with the fit/finish of this truck and donít have any regrets whatsoever. The only drawback with this truck so far is parking which can be a bear at times.
I replaced a 2003 F350 Crew Cab DRW LB 4x2 XLT Lariat with all the bells and whistles. Mileage is about the same as with the '03 7.3L diesel but the 6.0L has more torque and is noticeably quieter. Through 12,000 miles already and no problems to report. My spouse absolutely loves to drive my truck when I'm not using it, which is most of the time though. We are still using the '03 and it has 370,000 miles and still not using oil between changes and plenty of power! Just confirms my opinion that Ford really does build tough trucks.
Due to the extra purchase cost I got the gas v8. The diesel is needed for heavy pulling, but the gas V8 will do, just slower. Very happy with the truck overall though it did stall out completely one time for no reason and no code was recorded. The built in trailer brake system is a must for towing, but it does hold up the RPM's at times a bit too long and when coasting it will kick up and you have to tap the gas to get it to shift. But great overall. I can't even feel our 4 horse trailer behind it. The interior is very comfortable and large. The engine is thirsty. 12 MPG normally and 9 MPG towing. Fit and finish all are very good.
