My 2001 ford supercrew 4x4 lariat after 105k miles has never had any work performed except oil changes and transmission and fuel filter replaced once. I have pulled a trailer full of four wheelers from fla to central illinois, to southcarolina for years, and I have a 26ft pull behind camper as well. A wonderful truck. Barely looks used, even the leather seats still look brand new as well as the carpet. And yes, I'm an outdoorsman that loves to hunt. Catchall floor mats do the trick. the truck has the 5.4 triton motor, w auto.
