So I'm looking for a newer truck, im undecided between a '08 ford F-350 king ranch and a '08 dodge 3500 Laramie... Anyone have some input? Mostly used for towing heavy loads, I work in harsh cold winter conditions so it must be reliable for that... Also how is the fuel milage on both these units? The dealers can't give me any info on this because it varies so much with towing and stuff.
