Mud Flaps?
Look at post 14 above, blue truck. The angle in my pics do make them look a little lower than what they are. However, they aren’t much lower than the non retracting running boards. Plus being that close to the tire helps, but yes it could be a problem. Mostly only in deep mud or snow. I go off-road all the time in sand and regular hard pack dirt and it’s never been a problem. They do have a little give as well.
