Good find Bob.
Just because it is out of sight does not mean it won't break.
The other side looked OK?
I try to crawl under my unit even on the road, anytime I have some free time. Then when you hear a noise you have a better idea what it might be.
I was lucky on our Cape Breton circle trip in 2009 when, on a routine stop, I spotted a broken bracket on my rear waste hose box. If I had not seen it, and traveled the rest of the day over that construction on the east side, I probably would have lost the box. A length of bailing wire did the job until we got to Sidney where I purchase a length of 1/2" alumium tubing and secured it better than OEM.
