My 08 Sahara Unlimited came with running boards, naturally. I've had my Jeep for 3 years now and can't think of any time I've ever used the running boards. All they do is collect snow until it can drop off in my garage. That's obviously not going to be a problem for the next 6 months, but I can't think of any reason to have them on during the summer months either. I never use them to get in and out of the cab....all they do is pose a threat in getting my jeans dirty. I watched my wife get into the Jeep the other day and noticed she steps right over them to get in so clearly they have no utility in that respect.
Does anyone see any issue(s) in removing them?
