Michelle does not want an "aluminum can" as she calls it on the back of her truck. She's wanting the sleeker lines of a fiberglass model. We're going to follow our back-up plan and get a Leer 100RCC fiberglass contractor cap. It's rated at 400 lbs capacity dynamic and 600 static so it should work for us. I really like the idea of an internal structure without custom fabrication that the ARE HD offered though.
