That must be what they use the AWD in the race trucks? So the clutches can burn out? Do some research before you post BS...borg-warner has been using wet clutches in transfer cases for many years in many vehicles! They work fantastic and don't burn up as you described. I've put 350K miles on one with zero issues.Up to what you need it for, you can’t use Auto4wd off-road or you will burn up the transfer case from it switching on and off. I suppose it’s useful on the road on ice/snow but your really just revealing a poor set of tires for the conditions - it will get you moving with the wrong tires but won’t help ya stop with the wrong tires.
Fulltime AWD is infinitely more useful on road than Auto4wd. I would consider Auto4wd the system for the unknowledgeable. If you understand the conditions and inputs required then you’re not likely to miss the system.
If your desired setup includes Auto-4wd then by all means don’t avoid it. If your looking at a trim that does not include it then I wouldn’t spend more money to get it.
The only reason not to have a true AWD system with a locking center in this year in time is for the minuscule fuel economy decrease associated with keeping both sets of wheels driven. I feel Ford cheaped out on that.
Ford definitely didn't cheap out on the transfer case!
