The long-stroke 4.9 liter six is the best engine (most durable and trouble free) Ford ever built. But, I must qualify that. It is durable and dependable, and it has tons of low-end torque. But, it hits its peak torque at only 2,000 RPM, so it has nothing left at the top end. It strains to go faster than 60-65 MPH. The truck is a typical Ford. Even though it only has 61,000 miles, lots of little things are popping up. Door handle hardware, door fit, vinyl upholstery wear, window knobs, EGR valve, interior trim panels, automatic locking hubs, all have broken. I think a truck should be more durable than that, but it probably is no worse than a Chevy or Dodge in that respect.
Pulling power (I don't even feel my trailer behind me going up the mountain), smooth, dependable engine, dual fuel tanks.
More top-end power, better fuel economy, better quality parts (quit making door handle hardware out of pot metal), but all manufacturers need better quality parts. We don't like to be gouged for replacement parts that shouldn't break in the first place.
