2004 Ford F-350 Super Duty 2dr Regular Cab XL Rwd LB (5.4L 8cyl 6M)
I've driven 10,000 miles since I bought my truck. Still get valve noise until engine is hot. Mileage is 13.5 mpg when I try. The steering is very light on- center and is sometimes hard to keep straight on rough roads. I've had to take it back to the dealer four times for engine clatter when cold and for other drive train noise. On the positive side it has the best factory paint I've ever seen and the interior room is great. I have to wonder if the 'thin as water' 5w20 oil the factory says I have to use in the engine contributes to the valve clatter.
I really like the rugged suspension, ground clearance and the heavy duty 4 speed auto transmission.
The 5.4 liter engine really needs help when equipped with the 373 axle gear ratio. All in all I would buy another one but will get the extended cab and the 411 axle ratio next time.
