That was really odd. I've always heard Gobi is the "go to" in racks but clearly they have a design flaw in the JLU version. He had weight up there but significantly less then a roof top tent that many use that system for.I wish I had taken a picture of Todd's JL Rubicon with the cracked hard top from his Gobi Rack for others. That seams to be a poor design when doing that trail caused his hard to top crack in two places w/o hitting a object.
If you hear anything from him after he calls Gobi post it up. I'm curious if they'll stand behind it or push it off as user/install error.
