Bedside step: been here before.

[VTKidder]

I remember this from a while back; there was some discussion about a step built into the bedside on some fleetside trucks and whether it was a factory deal or not. I remember someone had pics of a blazer / jimmy with the step. There's a truck on ebay right now that has the same step. Did we ever conclude where these came from? I'd post a pic but I cannot right now for some reason Thanks all....
