There are few complaints about the Ford Super Duty's interior's space, fit, and finish, but comfort will depend on which trim you opt for.
Car and Driver, testing a 2008 Ford Super Duty with the King Ranch package, concludes "comfort was a clear priority inside the new truck." The package, they note, "adds baseball-glove-like leather seats among other sensual luxuries." Reviews read by TheCarConnection.com have similar views. Edmunds considers the seats "supportive." And USA Today reports, "Leather seats were quite comfortable, front and back. And the rear had generous leg and knee room." In their tests of the Ford Super Duty 2008, Consumer Guide points out that the "standard bench seat has enough space for three large adults, but is too hard and flat for long-haul comfort...Available twin bucket seats are more accommodating." They add, "SuperCabs have fine head room but very limited leg room, and the seatback is too upright to be comfortable. Crew Cabs offer vast head and leg room."
Over the years, as the Ford Super Duty has gotten bigger and bigger, it's also gotten taller.
Now the Ford Super Duty 2008 is so tall that you can't easily just hop up on the bumper and climb into the bed. Helpfully, Ford offers a stepladder that folds into the tailgate--which ConsumerGuide calls "a worthwhile feature." USA Today adds, "Supers sit so high that you actually need a step to help mount and dismount. So figure on steps or boards of some kind."
Edmunds notes that in the 2008 Ford Super Duty "plenty of interior storage is available via a large center console and generous bi-level door pockets." USA Today reports that an optional fold-out steel platform under the backseats "provided a good surface for heavy or dirty items." ConsumerGuide points out that Ford Super Duty 2008 "regular cabs have an 8-ft-long cargo bed [and] SuperCabs and crew cabs have 6.75-ft or 8-ft beds."
Edmunds says the 2008 Ford Super Duty's fit and finish are "unimpressive in our XLT-trim truck...[though] rattle-free." ConsumerGuide notes, "Materials range from stark to fairly fancy depending on trim level and options." Fit and finish levels appear to increase with the most expensive trim. As Kelley Blue Book attests, "the King Ranch enhances over-the-road comfort with material, workmanship and appointment upgrades."
As far as noise goes, Car and Driver states, "The traditional clatter of [diesels] is muted." USA Today concurs, saying, "The diesel was smooth and quiet enough for daily use," but ConsumerGuide reports "wind noise rises sharply at highway speeds." That shouldn't be a surprise, considering the Ford Super Duty is about as aerodynamic as a brick.
