We put one of the first run Powersteps on our Tundra for SEMA. They are extremely easy to install, they use four factory holes in the underside of the rocker. They don't tuck completely out of sight like say a Kodiak side step does. On a stock height Tundra they wouldn't be noticeable though unless maybe the truck was white. And that is a maybe.
The AMP steps are very good quality. I love the ones on our truck. I couldn't imagine having the lift without them now.
Here is the installation of the steps if you are interested.
