Roger Brown is a good man and he makes a fine product. I've been happy with my Sliderz though there was some problem fitting them initially because my early production 2000 Xterra has about a 3/8" difference a the front of the vehicle between the frame and the pinch seam than later models.

The ladder design has worked well for me and it sticks out just far enough from the rocker panel to allow for a toe hold to stand on.

The only thing I've had stick in the ladder is mud. This presents a problem for me when I'm washing the vehicle and have to get access to the underside of the rocker panel to clean. The space between the ladder and the panel is too small for my hand to get in there, so I have to spend more time than I'd like getting this area clean.
