ZEUS--- Yes, you nailed it on the head of the pin-- having the appropriate tires for the appropriate terrain is key. The reason why MARLIN was so successful at MOAB over Ldub was because MARLIN has the infamous 44 lb lightweight Grabber AT2 tires which go anywhere in all conditions; including sand, and yes mud. The Grabber AT2 is a jack-of-all-trades tire and highly capable in mud with its cavernous 17/32nds tread depth, whereas the mud tires are only a master of one but are worthless everywhere else (oh yeah, I forgot M/T tires "look good" LOL, tsk tsk). Lesson learned, class dismissed.
MARLIN--- I concur the SC route is a total waste of time and money on the VX. The VX-SC seems to be more of a novelty and opens a can of worms for other periferal things to go wrong with its proven unreliability. If the factory Isuzu engineers thought a SC was a worthwhile feature for the VX, then they would have included it from the factory.
OH NO, MR. BILL,... here we go again on the tires.............remember, to each his/her own....
