I'd have to agree that there is no winning, Mud is pretty much part of wheelin here. No matter what you do it is going to wear on the jeep eventually.
However, as I sit here, with my brake pads worn out in under 20k kms, my throw out bearing once again whirring due for failure, A diff filled with mud, a moody starter and another wheel bearing on the verge of falling apart. Maybe.....just maybe I'll take it easy on the mud from now on....
