Yes, it's a Weathertech BumpStep. It works well as a step, but I like it in case someone bumps into me, which has happened on my other vehicle and saved my rear door from getting smashed in. I also have the wider version called BumpStep XL (24" wide), but it was interfering with my back-up sensors, this BumpStep 12" wide one doesn't.
Loading and unloading in the rain (or hot sun) I wouldn't have anything other than the lift gate
But, the real reason for me was . . . . I drove a cargo van with the cargo doors and never did get used to the restricted visibility from the inside rear view mirror. I know it doesn't bother everyone, but I would never get used to it
