I find it funny that the wives are complaining... I'm the wife, hubby wants 'nerf bar' steps (as he calls them) on the 4runner for the kids. I don't want any sort of ankle-knocking extra stuff stuck on the outside. It was a hard sell even to get me to put aftermarket fender flairs on it, but at least I've been pleased with them. I had to deal with running boards on a Ford full sized van, hated the durn things. I ran over large rocks in our rural driveway all the time to try and tear them off, jumped up and down on the weakest points, etc. much to my parents' dismay. Only resulted in chewing them up a little.
BTW: My biggest complaints about running boards: they hold mud in inclement weather, messing up clothing if you should accidently rub across them exiting the vehicle. They hold water when you wash the vehicle, leaving something else to towel dry. They're ugly. They knock my ankles on entering and exiting the vehicle. They 'sissy-fie' the vehicle. Maybe those with wives who want them can reason with them on the mud/clothing issue ;) My kids don't need any steps, I'm strong enough to lift them into their seats and they're resourceful enough to get into the truck unassisted (even the 2 y/o, and he's shorter than average.)
