2008 Ford F-350 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
I pull a 13,000 pound 5th wheel, and this truck pulls it like it's nothing. On vacation this year, pulling the trailer all day at 75mph+ through Kansas in July when the outside temp reached 109!! No problem. Never had a problem, but dealer alerted me that radiator was leaking and replaced it under warranty. I never saw any evidence of a leak. The truck is like a cross between a muscle car, luxury car, and towing brute.
Tough decision. Stereo is best vie ever experienced. Brake controller is wonderful! Nav system is great. Mirrors are fantastic. But, the most important thing to me is dependability and performance, and I couldn't be more pleased.
I would say fuel mileage and cooled seats, but my understanding is that the new models have both.
