How much beating can the OEM FJ composite gas tank skid take? This is my biggest fear right now before hitting a few decent trails in the FJ. I plan to purchase a full skid package in the near future but until then, I just wonder if it is even worth doing any trails that would cause contact with the composite gas tank skid. I am sure there are plenty of you who have wheeled the heck out of your trucks with this composite skid. Let me know how it did!
