Ducktail is holding up fine. No rain on the rear window. Ended using a flat steel bar as the rear support and dual screws per side to sandwich the ends from moving. Only takes me an extra 5 seconds to pull the bar out and slip it between aero cap and the cab so I can deploy the cab cover.
Finally got around to hot gluing all the extra holes in the Coroplast so it will be nice and dry under the aero cap when it rains now.
Piccies when I git back home...
