Just picked up my box at Dave's saturday. Looks great, and solid construction.
Thanks for the install Dave!
For others asking him to modify it to fit other racks. While it's possible, it would take a fair amount of work as the box is optimized for the GS with the adventure case mounts. the box dimensions and shape, along with the mounting scheme are all optimized for the adventure rack...
Great guy! Good luck with catching up with the backlog Dave.
