My father in law has the oem running boards on his 15. After driving it a couple times, I decided to go with the steps on mine because the running board was getting the back of my pant leg dirty each time I got out. Just something to think about. The running boards look nice!
I had something similar on my '98 f-150 .I liked them because they kept the side of the truck cleaner .In New England my running board tubes get slush packed in them and sometimes its hard to open the door.
