The original poster doesn't appear to know any details, so I take it this isn't his truck.
Someone on FB asked him for details and he replied with this:
"saw a truck, it has running boards, I took a picture and posted it. Those are all the details I have"
So now the mystery falls to us. My monitor isn't the best, but it looks like the outer edge is steel tube with at least four perpendicular supports, so my guess is these lean more to the rock slider design and less to the flimsy plastic covers on so many U.S. half-ton trucks.
