I have a 2006 Ford diesel 4x4 my commute is 50 miles each way from my house to my shop and then plus the miles i put on it when im doing mobile jobs i have managed to put almost 16k since i bought the truck in febuary. Its and excellent truck and gets great gas mileage, i towed my weekend warrior with all the toys and wieghed it in el centro on my way to the dunes 22,260 pounds and was averaging 13mpg for the trip. I think they all have there perks and i feel better knowing that ford treats the customers on warranty issues better then others. on the 6.0 the have had three years to get the motor right so im glad i didnt by the first year and have to worry about being the ginny pig and take a chance of sitting on the side of the road.
