every manufacturer "makes" it thru with a stocker...what they don't show you is the stacking and team of dudes hauling rocks around to make that happen. I can also take my fat rig to a drag strip, doesn't mean it'll be the right place for it.Jeep claims they ran through with a stock Cherokee. I would love to see how that went.
sounds like you are prepping for the worst. that's the best plan.
