That's exactly what I thought too. Only the 4X4s have those two features. I've got to go back to the dealer and check this out.
I've always been taken by the 7700 truck which I see now includes a 4.10 LS on the 4X2 trucks.

wow
But that KR truck is just awesome looking. Especially in the Chestnut and Arizona Beige color scheme. Although I'm a fan of blue myself. I haven't seen the blue in person yet, I may like it. I have seen the Chestnut in person.
I've never had a 4X4 I may just bite the bullet and try it to see what it's like.
