I have had mine sine April '08 and have about 8K miles on it already, a lot of traveling out of town. However, I am very pleased with the truck i.e. its drivability, comfort,power, the rear a/c and plenty of storage inside and out. So, far not one problem.
Rear Air, trunk space,and the ability to lift the rear seat out of the way for extra storage.
More Horses, but it moves pretty good with the power it has, but I'm old school power freak.
