We are full timers and we installed thick carpet type step covers with a rubber bottom on our Kwikee steps years ago. We have no rust at all under them, gives us a 2nd place to wipe our feet off before entering the coach and they are a real safety feature in our book.
My wife had a coworker who slipped on her metal RV steps and fell while entering their RV and ended up fracturing a cheekbone. She now has the same carpet covers on her steps. Her metal steps before had just that partial no slip course area that most steps have. Our type of step covers are also good for those who have pets that like to scamper up the steps and sometimes trip or slip going up, especially when wet.
