I agree. 2wd offroading is a small cult of people, who usually have a 4x4 but like a challenge with their 2wd truck. I take out my 4x4 and tackle some obstacles. Then take the 2wd out and see how far I can get in 2wd. If you really think about it a 2wd with a locker is almost as good as a 4x4 with open diffs. I have been through some stuff that I thought a 2wd could never go. As for not having a low range, you have to gear low enough so you dont need one. I can put my 2wd in first gear, let the clutch out and walk beside the truck. Is that low enough for no t-case? Yes I believe it is. It works for me anyhow. And to see the look on those Jeep boys faces when you pass them on a hillclimb in a 2wd Ranger is priceless, making it even better when you sling half pound mud clods at their windshield.

A 2wd is not a rock crawler but I know one thing I have taken my truck places my uncles z71 would not go. And just the other night I was out and went right up a hill that a Scout with 35's could not make it up. It works for me.
One more thing, just think of a 2wd Ranger with a locker as an oversized 2wd utility or sport quad. They can go everywhere.
