Hmmm, are you talking about a metal shroud to enclose the fresh water tank? Do you have the front dinette model we have?
I don't think we have one either, maybe that's the design. We're inside the trailer at Airstream Jackson Center, OH right now. It's raining, soon as it stop s I'll go out and check a few.
Leaks. Get a moisture detection meter such as a Sonin that Amazon sells so you can go around the interior perimeter, probing through the vinyl into the wood subfloor. I do it quarterly and have found several minor leaks that otherwise are completely undetectable until the subfloor rots. Of course if your sitting inside while raining and it drips on your head, you have a leak.
This morning Airstream pressurized the trailer then used a soapy liquid outside to look for bubbles. They found a few small ones, which confirmed what I found with the moisture meter, and fixed them. The Service Center here is wonderful.
My leaks were below the entrance door hinge (tightened screw and resealed bracket), two of the lower awning brackets at the rivets (sealed), below hinged rear window lower corner (tightened latches). The rest of the trailer tests watertight. That's pretty good I think, but checking quarterly with a moisture meter would save you headaches down the road.
Interesting about the awning mount leaks. Took the factory assembly tour and watched the water leak test where they spray the whole trailer shell with water under pressure. After done they move along to get all the equipment installed, including drilling holes to install exterior awnings. Other than that, the assembly and sealing looks excellent, very encouraging.
