I have taken mine to some pretty rugged construction sites. Had to climb a ramp with around a 30% grade on it, truck did fine, but one rock came loose, and banged all along the skid plate as it rolled under the truck. I had to crawl under to look once I got to the flat, somewhat panicked that I could hurt something. Luckily just some light scratches, nothing to worry about.
Same site had a soft sand fill that hadn't been compacted yet, drove threw that, and picked up a bunch of sand in the wheels. The truck had a noticeable shimmy until the sand worked its way out. Also went threw a water crossing on the same site (before going threw the sand), water us over the running boards, my passenger joked that if we fry the truck in the water it will be a bad look. Water didn't seam to do anything, so that was good. All in all, its gone everywhere I would have tried taking my old F150, so can't complain.
