I think the mounting location can handle some weight. My wife is around 140 and is able to stand on the plastic OEM bumpers. The bumpers bend but nothing metal does. I'm 260 and I can put half my weight on them (one on a door and one on a bumper).Wouldn't the issue not be the fenders but the mounting locations? If they mount like the plastic fenders then they would just rip your quarter panel to shreds as the rip from it under weight.
