Toyota bed + toolbox = not enough room for a bike. i have some mounts on the toolbox for my QR bikes, but my Spot will be a 20mm TA. i'm thinking about trying to fab something up such that the bike will sit above the tool box and bed, using a Yakima (King) Cobra. has anyone done something like this? i know Yakima and Thule make artificial rain gutters, but once it's all said and done, that **** gets expensive. i'm trying to make something such that the only piece i'd need from Yakima would be the (King) Cobra.
