2008 Ford F-350 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
This is my first diesel truck and upgraded from an F150. This truck has tremendous power and towing ability and looks the part. Just got back from an extended trip towing a 10,000 lb trailer in the mountains with an 800 lb motorcycle in the bed and the truck did great even after obliterating a deer at 60 mph. I did develop a funning turbo noise under extreme load and high rpm towing which is a concern, but have not had any other problems. Mileage under load varies from 7.5 to 10 mpg depending on wind and speed, but unloaded I have gotten up to 19 mpg at 70 mph which is better than my F150. It took about 5000 miles to get to that mpg.
