TX_TLC,
The step boards are more than that. If you look at them onnly as " damage multipliers " you've failed to open your eyes. They are the first warning when you've made your turn too tight against a root, tree trunk or rock. They reduce the muck that flies against your doors, helping your paint last a little longer. They are the helping hand for that tired step at the end of a long day, either for yourself or a cherished elder. They also make it easier for your precious little children to climb into your entertainment center. Maybe it's easy enough for you to flex that extra inch and a half higher, but not necessarily for all the people with you. If you experience damage multiplication with stepboards, it's only because you asked them to function in a task they were clearly not designed for. That's like asking your 7 year old boy to change your tire.
Perk didn't appear to be ready to put on sliders. He wouldn't have asked the question if he were. The simplest solution is to buy new stepboards. For sure, if he paid attention, the fact of the stepboards striking an obstacle would have caused him to take action to avoid further damage, or try to do so. Regardless of results, the stepboard would have served a valuable service it was not designed for. I would surely keep one on my LC until such time as I could replace it with a slider that also served as a step board.
