Triathlete pointed me to Stric9 Sliders. I got them and had them installed this week. Same general design as the RR super sliders. I think they work the same as a step bar. I hate step bars and don't use them, but they rub my ankle the same when I get into the vehicross now and my Borrego with side steps. Really nice for access to the roof! If you make it to Uwharrie this weekend (nudge) you can see them for yourself.
I don't have pics yet, I will be posting them next week after Uwharrie.
