My brother just had to get a new truck, because of a fender bender, where the insurance company totaled the old one for a front fender accident! He bought a big 2008 Superduty F250 Lariat 4X4 Crew cab , with a diesel that has two sequential Turbo's,he say's so far highway fuel mileage is around 18mph. Damb good, since our little 4 banger Toyota 4x4 gets 20 and it would almost fit in the bed of his new beast! It seems since coming home from Iraq, life just keeps throwing more hurdles at him, but he loves the new truck!
