I have a 14 crew cab 1500 5.7/8spd

I do not have the fulltime t case.

No problems with my truck, I tow a lot with it, and drive it in all bad conditions. The 8spd is returning great fuel economy. on stock size tires I was getting 17/21 now I get 16-17 on 35s I also don't drive gingerly

Mine is a basic tradesman with the all the tow package options and the 5.0 radio. I highly recommend the built in brake controller if you are going to tow a trailer with electric brakes.
