I would not say so as a absolute. Not a good choice for rock crawling though.

id say you could go further threw rocks with a well plotted path, than through nasty mud. back on subject, open diffs allow wheels to spin at different rates to reduce tire where.

GOOGLE!

An open differential allows for free slippage between the two sides of the axle. When a car is turning, the inner and outer wheels must rotate at different speeds. If they are forced to rotate at the same speed, there will be increased wear on the entire drivetrain and tires as the slippage needs to "rubbed off" somewhere, normally the tires. An open differential allows for some slippage to occur between the two sides of the axle so that the tires do not rub the ground

There are two school of thought here. One is to have the axles locker together and the other is to let the trie with least tractio sping and clear itself and get a better bite and when this happens you can feel your 4x4 "walk" through the muds searching for traction rather than burying itself with all wheel at once. No one rule fits all in this area. Myself I never liked posi much on my 4x4's because I spend a lot of time on snow and ice working and a open diff has better directional control on these surfaces.

Absolutely right you are. Driving on ice is nothing like driving in mud. If you think you can "walk" through a serious mud pit spinning only one tire on each axle you're high on crack. You think the tires will "search for traction" with an open diff? WRONG! All that happens is the tire with NO traction spins. What good does that do you? Then you have another tire completely full of mud that acts like an anchor, won't clean itself and won't give you any forward motion. Besides, you should know that torque steer is going to cause one tire to pick up off the ground anyway.

Once again you seem to think thousands upon thousands of guys who play in this stuff every day don't have a clue what they're doing. Guess again. You're always ranting and raving about sharing knowlege and all you seem to want to share is BS. Do us all a favor and keep it to yourself.

Oh. My. God. When will the insanity end

No, there isn't two school of thoughts here. In mud, the more wheels you have with positive engagement the better, end of story. I can't believe you even compared it to ice, which has opposite requirements. Do you just make this stuff up because you're a masochist or are you just clueless but feel better about yourself by trying to sound smart This is starting to rub me the wrong way since you've been here less than a month and so far every single thing you've said in here has been wrong. Which wouldn't be so bad, other than the fact that you keep saying you are this master mechanic expert who's done it all and is in the right

Myself, I like to just remove all 4 wheels and let the drums and rotors pull me through the mud. I works great for me and allows all the torque the three hampsters on the exercise wheel connected to the tonka truck transfer case develops to really pull me through the pits of mud that Pro's 44s can't handle. I mean really, who needs gound clearance or traction to get through the mud anyway. All it it takes is to be a master something and have a carrot for a nose.
