That's valuable information and, one that needs to be a part of one's annual checklist of some sort.
My personal experience:
Just after I had my "seg. protectors" install at the factory, I had pulled over for a short rest spell. (About 140 miles from the factory) As always, I walked around the unit, feeling the wheels, etc..I noticed that my brand new "seg. protectors" were just begining to rub against the curbside panel. Upon further inspection, I found that the panel hadn't been properly installed at the factory..In that, only two screws were originally installed instead of 8 or 9 (these holes hadn't even been drilled ~). One was at the top and, the other one at the bottom. Well, the one at top was gone~! The one screw left was lose.. half-way out~!
Fortunally, I caught this..otherwise, I could just see this "seg. protector" panel opening like a parachute...ripping off a big tear in that panel...I refasten it down with some screws that I had picked up off the ground from the factory..
I called Rick March and, together we spoke with the Service Shop manager about this problem..They did send me a package with the optional tiedown bracket, etc.
