Personally, I don't like anything "hanging" from a car. I like it really clean. I removed the emblems, and front mud flaps first (as part of the trimming process for tires) btw - I just removed the rear muds too. Then, I removed the running boards (temporarily) as I was getting ready to acquire another member's steps. I ran a few days with out them and actually like the look (does make it seem higher). But after having a 3rd gen with running boards for a decade, complaints from the wife, and being able to "see" too much of the trailing arms, etc. I decided my move to the steps was the best of all worlds. Now, I can wash my car quicker, have steps for my wife, and give added protection to the rockers (a plus is that they are lighter and don't stick out as much).
2 cents...
