Tons of good advice here. I got my first 4wd in 1997 (Toyota 4Runner) and have owned nothing but a 4wd since. 4Runner, Tundra, Tacoma, and two GMC 1500's.

Best advice is 4wd will help you go but will not help you woah a bit. Don't be the guy going 70 on a snowy road, you don't get any sympathy from me when you ditch it.

4lo is a rare need but 4hi is good to use on slippery stuff. I've even used it climbing out of some of the steep gravel roads out of the Buffalo River valley just to keep from spinning and bouncing all over.

Both my GMC's have had the Auto function on the transfer case that will kick the fronts in if the backs spin. I've used that a bunch in the city when trying to turn into traffic on rain wet streets from a stop.

I've never had a moments trouble out of the 4x4 systems. Just remember every now and then when on a gravel road to kick it into 4hi so everything gets to turn over and work from time to time if there are long periods where you don't use it.
