Yep,
Got 'em installed last month for about $1100 out the door. I live close amp-research and there are a few local installers that give better pricing than purchasing directly from amp-research.
As far as the steps are concerned, they work very well. Very sturdy and while retracted, are almost completely invisible. They extend very quickly so there is almost no waiting period to step into the truck after opening the door. In addition, they have safety circuitry built-in, so the steps will not retract if someone is standing on the running board.
