Custom bumper storage cover
I seem to remember seeing a really nicely designed bumper storage cover someone fabricated out of thicker aluminum to replace the original Airstream cover. Does this sound familiar to anyone? The cover on our '64 fits the category of "dumbest Airstream design/what were they thinking", being designed so that water channels towards the rear edge of the plywood floor, as well as into the bumper storage. The cover itself is thin, like 18ga metal. The retrofit I remember seeing was far more robust, with a sloping cover to shed water over the bumper, and more sturdy cover latches. I've come up with a replacement design which our local sheetmetal guy is pricing for me (holding breath). Here is a picture of part of our cover, without the belt trim and the half of the hinge that mounts under the belt trim.
