i see those slider steps on photos of non-US cruisers all the time. are they sliders? steps? running boards? OEM? aftermarket? i can't figure it out!
OEM for everywhere 'cept the US i think, i guess they're step/running boards, they mount via 4 brackets to the bottom of the body.
They do provide moderate protection, but in general are pretty useless if you suddenly slide onto of a rock/log.
