I should add though, that chains are amazing. I know for a fact that in some deep snow and even some mud situations, a 2WD with chains will get farther than my Jeep without chains. I've seen me do it.
But there are other situations, lots of them, where wheelbase and ground clearance are what makes the difference vs. raw traction. Washouts. Steep cut banks from recent flooding. Ledges. Big rocks. Sand dunes.
And any time you are getting a rear tire in the air, that front axle pulling is real nice too. Steering in bad mud, front axle is a legitimate asset. Steering on anything real slippery, it's nice to have the steering axle pulling.
I wouldn't be without it. Just don't see any reason not to.
