2003 Ford F-250 Super Duty 4dr SuperCab XL Rwd SB (5.4L 8cyl 6M)
I have a 7.3 diesel. It's a wonderful hauler! The truck is very stable when hauling 2 yards of dirt or our 5th wheel trailer. I haven't modified the powertrain and see no need to. The economy of the diesel is about 14 in town and 19 highway; and about 11 with the trailer. Top build quality, over 100,000 miles and no squeaks. If you need to move heavy stuff, this is the one. If you only want a truck to look cool, the half-tonners are better for that. This is a serious work truck.
