Being a creative tinker.. when we needed to carry a few thing outside the jeep.. I purchased a metal tire mounted bike rack, angled the arms to support a plastic storage box, mounted the box with U bolts and let it go.. The issue I ran into is when the rack would bounce around.. the load would shift to one side or another.. it's like I couldn't keep the straps (which held the rack onto the tire) tight enough. We don't like those rectangular metal trays that mount into the hitch receiver.. they stick out too far.. The only other option is to install the HighRock storage tray system within the open area of the roll cage behind the rear seat. Along with this.. Highrock has an alternate mount that can be located just above the open area for a small roof rack. But the issue with the rack mounting hardware is that it is very heavy.. made with powder coated steel tubes.. I'll be redesigning this setup and incorp aluminum lacrosse poles as a suitable and lighter replacement.
