I've got a 96 Dodge Ram 4x4 with the 360. I don't go off-roading with mine, per say. I have no reason to tear it up. I depend on it for regular transportation too much.
However, I DO drive in my fields (on my ranch) and through the creek beds and through mud to get to my barn and count cows and such. I also have to use the four wheel drive to pull my 22" offshore fishing boat out of the water. It's quite big and heavy and a regular truck can't really do it.
So those of you who are all up and riled about all the soccer moms and such that never leave the pavement, and who think that a 4x4 should be used to go out "mudding" may be overlooking the real need for one. Those of us who actually use the 4x4 feature for daily/weekly/monthly work duties and activities. Don't get me wrong, I think it would be fun to go play in the mud with the big mudder tires, but for me it would just be wasteful and potentially damaging to my truck. Maybe I'm just too practical, but I don't really feel I have anything to prove by getting my truck scratched up and muddy every weekend, or whenever. But I certainly like to see others out enjoying the sport. It looks like a lot of fun.
