Ive been trying to deal on a at4, no luck at all just my supplier and the 2500 rebate they have beyond that nothing, noticed that some elevation crew cabs have come around, also noticed u can get max tow, and a moonroof, that maybe the route i take, i bet the 5.3/10sp/3 42 is a nice setup. My 5.3 3.42 tows my 9000 pounds very well, 10spd will now have a year out with gm, specwd to my liking around 54300, vs 62k for the at4 with 6.2
