Folding receiver hitch mounted rear step, Anyone seen these?

I managed to locate one of the fleet trucks that I had originally spotted on the freeway. This is not the exact step that I saw but it is a nice dual step folder made by CC Industries LTD in Vancouver B.C.
but I haven't called for a price yet. The company that uses these in their fleet is Leavitt Machinery a forklift repair company and I plan to keep an eye out for other versions of this step
