I ended up puttong padded boards in the "boarholders" in the bed-liner. After talking with the folks that built my canopy, I am also going to make some brakets that I can attach near near the canopy ceiling to hold flat/light things like wing sections. turns out that I can just back a ccouple of the screws out that hold the window flange in, mount a flat metal bracket, and run the screws back in. Neat and tidy and gives me a THIRD level of racks!
