4x4 or 4x3
This is just something I thought of. I've never owned a 4x4.
If you do not have a limited slip differential on the rear, that means only one rear tire has power at any given time. Well, if you have 4wd, how does that other rear wheel get power?
I was under the impression that the transfer case only allowed the transfer of power to the front 2 wheels.

deep6blue,
If you truck is stock, and you don't have a limited slip rear differential, only one wheel gets power. The front axle on F-150's has an open differential, only one wheel gets power, so really you have a 4x2. The transfer case provides power to both axles, the differential decides which wheels get it from there.
With a limited slip differential, it provides power to only one wheel unless the drive wheel starts rotating faster than the other. Then it gives a percentage of it's power, up to about 40% or 50% (it varies based on manufacturer) to the other wheel until the uneven rotation stops. A locking differential gives 100% to both wheels if one wheel start rotating faster than the other, this is great off-road, but very bad on dry pavement. Because when you turn a corner one wheel always rotates faster than the other.

I don't think I want this technology on my truck.
We had a little talk going on out there. We had two trucks, the other was an 02 F-150 FX4 SCab. The F-150 drive looked down a rough road, and said to the Yukon driver: "That's a good spot, but we can't drive it today, you'll neve make it." The Yukon driver wasn't going to take that and I thougt we were going to be headed down that road for sure. Never did though.
I suppose it's a good thing, as the F-150 driver was talking from experience, and the Yukon driver didn't know any better. Main point being the Yukon didn't have the clearance.
