What's in there?
I'm wondering how many Airstream coaches have the boxed-in rear bumper, which, on my rig, is where a big flexible tube is stored. My question is this: Inside the boxed in bumper, there is a sheet steel box that surrounds an insulated fiberglass tank, and the sheet metal has rusted out. I'm thinking of replacing the sheet metal part I can see with sheet aluminum, riveted in place with 3/4" aluminum angles. The fiberglass tank is obviously the black water tank. What holds this in place? At the rear, where the sheet metal has rusted out, there is a piece of plumbers tape which appears to hold up the tank. The plumber's tape is all but rusted out itself. At this point, might the belly pan be holding the tank up? Has anyone seen a great repair for this, and any sort of retrofit for the leaky bumper-box cover?
