2008 Ford F-350 Super Duty XL 4dr SuperCab SB (5.4L 8cyl 6M)
I have 1200 miles on F-350 Super Duty with 6.4 Power Stroke and I have already seen 15 mpg at constant 65 mph with cruise. I see 12-13mpg in town. Truck tows like a locomotive...rides like a car. Best ride in any dually out. Leather seats are comfortable, cab interior is carlike. Stereo sound is great. My wife likes to drive this truck better than her SUV...speaks volumes about how well it handles. No diesel will give best fuel economy till at least 5000 miles.
Cab Interior...6.4 Power Stroke...carlike ride...great audio system...good build quality and fit and finish. Truck is very quiet.
Get fuel economy up to 20mpg and this is the best truck for the money on the planet.
