Powered Bed Step?

At my dealership recently, I saw a Tundra in the service department that had a powered bed step that extended when the tailgate was opened and retracted when closed. I was wondering if something like this exists for a Tacoma. A cursory search didn't bring up anything.

 

Yes, AMP Research make them for Tacomas. I had one on my second gen, but when I got my third gen, I decided not to. Kinda spendy though.

Thank you for this, but I think I need to refine my question. I meant a step that retracted under the bed near the tailgate.

 

If someone does make one it's got to be crazy expensive since the manual one is $200.
