We took a bone stock Rubi through last time there. He ripped off a rear fender (could've been avoided if it weren't for a bad line and rain) and he bent/scraped his chintzy dealer installed step rails. If he had the Rubi rails on there, he might have a scrape still, but no real damage. So no serious damage, just replace some fender clips and shiner her up. If the weather's better, I think you'd be fine.
