I've had it at mid-perch for 80K of the total 85K miles and everything is excellent, no problems associated with that or from the tuner, tires, CAI or exhaust. Like I mentioned in my starting post, the truck has just gotten stronger.
Having it at mid-perch with the Toyo MT's gives it a very solid feel. The additional power from the various mods fit hand-in-glove with this superior handling. I'm sorry to say that I don't think I would enjoy driving a Raptor right "out of the box" nearly as much as this one. I'm sure others with similar mods will probably be in agreement on this point.
The interior is without fault except the surface of the driver's seat was just starting to show some wear when I covered the front seats with sheepskin. BTW, black sheepskins look very sharp in the black trucks.
I should have been out shopping for another Raptor 15000 miles ago, but I just can't find a reason to do something like that...
