Shopped around for quite awhile till I found what I wanted. It was on order, and I got lucky and put money down on it.Yes its SLT, the AT4's were selling for over MSRP in my neck of the woods. I liked the grill and wheels over the denali..I'm a simple kind of guy.. As far as the constraints on the 22's, I'm not sure. I haven't heard of a date they are going to even start to ship them.
