Yup, built it myself. And also, since these pics, all the u blots are facing downwards and trimmed off. You can see it in the last couple pictures. Also put a small piece of rubber in between the rack and factory roof rack rails.
The thing doesnt budge, I've tried yaking it back and forth totally rocking the truck and the rack doesnt move at all.
I'm planning on putting some new lights up there as well, some rear facing fog lights and who knows what else.
