Haven't used em or seen em installed. But I went with solid (PS RockerKnockers) that catch the frame AND pinch seam for strength - I can jack the entire side of the rig up with my sliders.
I think these would be okay for a mild off roader - but the first time you get em really hung up on the rocks - dont expect them to be fully functional anymore and as they only mount to the pinch seam and floor - could seriously damage the pan if really hammered on...
