Hi, I fitted a set bought on EBay for about $350, easy to fit, I would in hindsight not fit them, as they make getting out a pain in the butt, you have to reach out over the step. Not comfortable, I was talked into fitting them by a mate.
This has nothing to do with running boards, but I am too short to get into the front of our motorhome so my husband made me a wooden step with a long rope handle which I place in easy reach when I get out the van. When I return to the vehicle I just place the step on the ground, hook the handle inside the vehicle, step up into the vehicle and pull the step up using the rope handle and put it away till next time. Problem solved.
Hi Nuk, we too have a Jeep GC and I had running boards fitted when we brought it and given my time again I would do exactly the same. They look good and are very functional. Go for it.
