VPR 4X4 Rock sliders info...

has anyone heard of or used any of their products, the rock sliders are a style I am interested in, but can not find any more info in them... I am looking for a dual purpose slider (short wife) and so far I am leaning toward the Demello x-wing or Crusher, but I like the look of these and if they are a frame mount I might be interested, but if it is a glorified side step....then why even change out the big pontoon steps that came on my truck...

They look like they mount to the body. I'd say glorified steps, but you should just call them to verify.
