I read that buyers will have the choice of either the BorgWarner 48-11 (on demand 4wd) or the 48-12 (part time 4wd). I have seen picks of Limiteds, Laramies and Bighorn models with the 48-11 transfer case but all the Rebel pics are missing the button near the shift knob indicating Auto 4wd. Has anyone tried ordering a Rebel with the 48-11 transfer case?
