IMO it's a truck if its rainy or icy and you think 4x4 will help I would say better tires are in order 4x4 makes ice more dangerous ie. front wheels spinning = no steering on ice...... On the other side of it if you can't tell when you actually do need 4x4 as rodlg35 says buy a Subaru. I am sure there's engineering to make them work properly but there is no argument that while your tires are spinning and it kicks into 4x4 no matter how much effort goes into making it work right that isn't good for stuff obviously proof on the Tahoe (even tho its a chev) any ways to sum it up its a 4x4 not an awd leave that for the fusions and the flexes and buy your self a 4x4

Based on that read, it's a proportionally controlled variable torque transfer system, which sounds like AWD to me. I wouldn't run it all the time, but I wouldn't hesitate in inclement weather.

I have a 2012 Lariat 4x4. This trim level comes with the "4A" setting on the 4x4 dial, which is the AWD setting.
AWD on the F150 is "on demand": it defaults to sending all the torque to the rear axle, and when it senses a loss of traction on the rear axle it diverts as much torque as it senses is necessary, in 10% increments, and up to 100%, to the front axle. The front and rear differentials are open, so if one wheel on an axle loses traction all the torque will tend to be sent to that wheel, but the traction control system senses this and applies some braking force to the spinning wheel, thus diverting torque back to the non-spinning wheel (the one that still has traction). Thus any wheel that has traction, even if it's only one wheel, is going to get torque. This system is safe to use on all driving surfaces.
I tend to leave it on all the time. Despite what the manual warns I haven't noticed an obvious gas mileage drop. I like it because I do a lot of driving on gravel roads and with an empty bed, and with AWD on I never spin the rear wheels. It makes fast starts very nice. I also find that it works very well in deep, sandy soil, so I rarely have to switch into 4x4 mode.
Hope all that helps.

I don't think you can get limited slip rear end at all anymore but they have electronic wheel slip control that uses the brakes and acts like limited slip which was a new feature in 11

I don't remember exactly, but I think this is correct: When I chose the 4x4 option AWD was included with the Lariat trim level. Then I had a choice of rear differential: Open, limited-slip, or E-locker. I opted for the offroad option which included skid plates, an open rear differential and an E-locker on the rear axle.
So I THINK I could have gotten a limited slip rear differential AND the AWD if I'd wanted it that way.
But I figured that the traction control, which senses wheel slip on an open differential and applies braking to the slipping wheel, does a good simulation of limited slip (as long as the brakes don't overheat), and that if I really got into trouble offroad a locker would be the best tool to have.
