I put two cargo rods with pipe insulation on them between the top and the bed. The rods are like shower curtain rods only a little heavier dutty. I put my wings on top of the rods and just set the fuses under them. I have a bungy stratched across the bed and the landing gear is attached to it with a even smaller bungy. A 4 Star 120 with one piece wing will fit this way and my truck is a short wide. The rods come out easy enough and easier to store than purpose built PVC racks.
