Our 2020 Winnebago View was missing the supporting strap for the waste water pipes. I'd heard of these pipes falling off, so I temporarily secured the assembly with a ratchet strap.
I sent pics showing the pipe assembly was not supported to Winnebago Customer Service and they sent the missing strap and ring.
The two parts arrived quickly, but still needed to buy a 3/8-16 bolt and two nuts.
I bent the ring holder around the pipe, and discovered the strap is too short and doesn't fit to any attachment point, so I made one from 3/4" strapping.
Once I had all the holes lined up, it went together quickly. I don't have to worry about loosing the pipe while going down the road.
