The steps keep ALOT of road crap off the side of your doors. The little black plastic mudflaps do an ok job, but the steps really take the brunt of the road debris. Keep that in mind.
I like the look of having the steps off, but then when you stand sideways to the truck you can see all of the undercarriage hanging down, not cool.
Also, be sure and spot paint the holes when you take the bolts out. You have raw metal where the bolts where attached to the frame. Rust will appear overnight, especially now during the winter.
