2001 Ford F-250 Super Duty 4dr Crew Cab Lariat 2WD SB (5.4L 8cyl 5M)
This truck pulls an 11,500 pound trailer - it has pulled it through the Appalachians, the Black Hills, and the Big Horn Mountains without any trouble whatsoever. It exudes power. It has been trouble free for 71,000 miles and has many many more trouble free miles left in it. What a great truck!
Power, styling, room, comfort - heck it even gets 17.5 mpg in daily driving which is city and highway mixed.
The ONLY trouble I've had with the truck are the front door actuators that pop the locks. At 4 years old they have given up the ghost and I will be replacing them this weekend. They should last longer than 4 years!
