For 13-14, the Bighorn/Lonestar, Sport, and the Laramies get the on demand auto transfer case. The tradesman, express, SLT, and Outdoorsman are all supposed to get the part time case, regardless of frame length. And you're right, it's not really an issue for 99% of folks but it is for some. I believe the 09-12 trucks had an NV case rather that the Borg Warner a D 4lock and 4Low actually locked up like they were supposed to. The problem with the new Borg Warner case is that 4 auto is really no different than 4 lock. It must detect wheel spin before engaging the front axle.

I've already experienced one instance that pissed me off. Had my little flat bed trailer hooked up, parked on an incline, rear wheels on soft mushy grass, front on hard packed gravel. I put it in 4 lock, gave it a little gas, and it dug a nice rut with the back tires before the front tires ever got any power. The rears should have never slipped with the front on gravel and in 4wd...
