Can anyone that's taken delivery of an LC250 with the OEM Rock Rails give me your take on their quality? My incoming 250 will not have these installed and already I'm seeing new owners looking to sell the ones that Toyota or their dealer installed (for whatever reason, maybe they don't need sliders, maybe they have their own preference for rock sliders). I want basic rocker protection (don't see myself navigating boulders any time soon) and it looks like I could score some sliders for less than half of what Toyota wants for them. I'd just like to hear if they're junk or not.
