Living in the mountains, we do get some bad weather. I find it comes down to two things for me on Ice and Snow. The right kind of tires is number one with me, I find traction tires on the rear (mud and snow type) work best for me in the Snow and on ice, plus I carry snow chains, but yet to use them.
Number two for me is weight over the rear axle (sand tubes or bags). This is a big deal with me, owning a pick-up. I really think any model body may need some extra weight in Winter as they all seem so light, just for traction. I figure the weight of two people or about 300 lbs. in back of mine.
In rain, I use Rain-X on my windshield, plus I do not ever go real fast, even though my truck could only do the speed limit anyway, but in rain that can be still too fast for conditions. Just my 2¢.
Good Luck and Be Safe!
