Mud is great, some kind of mud tire is a great help too.
I run 4 low lock w/ rear locker engaged (note above 25 mph the rear locker will disengage so after a blast thru the mud u have to lock it back in).
Muddy hill climb I had the TC in normal and the brakes kept pulling the motor down, so the others I told to use TC2 for more tire slip before TC starts braking.
Drive it like u stole it helps too, the big chunks of mud will wash off the top of the roof
