2005 Ford F-250 Super Duty 4dr Crew Cab Lariat Rwd SB (5.4L 8cyl 6M)
As of Dec 2011, I have owned this truck for over six years.
It was bought new and I haven't experienced any problems during this ownership.
The truck is used to pull a 24ft boat, large horse/cattle trailer, and utility trailer.
Excellent interior space for front and rear passengers, more than ample pulling power, smooth transmission shifting, dashboard layout is exceptional, and multiple positions for rear seat storage/hauling/seating.
As some posts mentioned gas mileage - a heavy duty truck was designed for pulling and hauling which makes gas mileage secondary.
My next truck will definitely be an F-250 Lariat.
Cup holders, console storage, pulling power, sound system, electric sliding rear window, quiet ride, rear seat diversified positions for passengers and carrying heavy objects, front mounted tow hooks, large outside rearview mirrors, and vehicle's computer information center.
