My Axis already had mudflaps but the passenger side one could hit the exhaust pipe and melt the mudflap.
So I picked up some mudflap weights from https://www.iowa80.com/exterior/mudflaps where you can also purchase mudflaps (and chrome....lots and lots and lots of chrome LOL).
My Hurricane came with mud flaps and I thought I wanted one of those things that hangs by the rear of the coach with our name on it. After searching this and other forums, I learned the mud flaps were sufficient. The search feature really helps.
