I am in the procewss of replacing that part of the U channel and would like to do it right. The last picture was of the U channel that the sheetmetal shop lost and you can see how far it went. I think it was cut off and needs to be longer. The other side only has a gap of about 4 inches. What do you folks think.
You don't need any C-channel at the water heater opening. Mine was flattened with a hammer by the factory in 1964
. If you are missing part of the curved C-channel that is not in the WH opening you will need to contact Airstream for some new material. If the C-channel is not riveted to the skin AND bolted or screwed to the floor, it's not really doing anything.
Your WH cutout looks strange. Mine's just a rectangle.
