I've had 2 250's, an '04, now a '13 and live in the Northeast. As with most, I only use 4 wheel high when it's snowing and there is snow on the road. Interstates or local roads, if there is snow on the roads it's 4WD high even if it's "spotty". The only time I use 4WD low is pulling someone out of a ditch. That being said, the '04 hopped quite a bit more than the '13 does. It decreases if you're moving, my experience has been the faster you're going the less the hop - maybe you just feel it less. Backing into parking spots, maneuvering in a parking lot / under 20mph it seems to happen a bit more. As with most, when I'm in a parking lot or in other situations under 20mph I try to use 2-WD unless I'm slip sliding away.

 

I mentioned using 4WD even when the roads are dry on the mountain where I live.

There are a couple of spots where the rear just spins in 2WD. And the rear is limited slip, so the back of the truck heads in whatever direction the road slopes.

Of course, the places where the truck has traction issues are also curves, so it hops. It is not good for the truck, but neither are ditches. I think the grade at those spots is at least 20%.

But with the right tires, 4WD Hi with a LS rear in the snow is fantastic; I just need to get the right tires on my rig LOL. It needs help on dry pavement.
