Can you make the same design out of aluminium sheet and aluminium frame (cube lock perhaps) instead to keep the weight down?[/QUOTE]
that thought had crossed my mind, and I could possibly just weld the frame onto the tailgate - using the tailgate as part of the structure. But i was worried that the price would be prohibitive..... maybe I need to look into it more - figure out what I would need and how much it might really cost
