Need some ideas - waterproof rooftop cargo carrier on ARB full length rack
Hi, I'm looking to integrate some sort of waterproof cargo carrier onto my ARB full length rack. I am thinking some sort of rigid plastic rooftop carrier, but I want it to be about the width of the interior of the ARB: ~40". Ideally it would be no longer than half the rack, so link 40" or so. I would like a bonafide cargo carrier for the aerodynamics, but would also consider military surplus Hardigg cases, if anyone knows where to find them.
Any ideas? Post your pics if you've done this!
