Rack is looking good man! Glad to see it's being used even if it was as a battering ram once lol.
I'm not too worried about Gobi. These are my personal pieces of art that I built for myself. Each one different from the last. It's just a bunch of scrap metal stuck together that just so happens to bolt to other metal that bolts to the roof of 4Runners. I can't stop people from storing stuff on top of my artwork lol.
The front can free float or have adjustable rubber feet with felt bottoms. No issues of denting or hurting paint.
