I think what Mike is referring to is a Thread-cert or Rivnut. These are nuts that are somewhat like a pop rivet. Drill a hole, pop in a rivnut, then you can bolt to sheet metal. This the how Thule and Yakima attach their aftermarket tracks on roofs and shells. Works well and Jeep obviously knew their roof structure and the places to bolt to.
Autohome came up with the "universal" mounting system back when roof tents were mounted in safari style roof baskets, it is now industry standard. The idea is to make a very light rigid base then the tent can be mounted using sport bars. In the case of the Columbus, the fiberglass base has all the strength, the metal tracks are really for mounting and you could probably take them off and it would be almost as strong, more flex but shouldn't hurt anything. It is a very strong system, a cored lamination, fiberglass with a bonded foam core, like the deck of a fiberglass sailboat. So, short answer is yes, you can put an AutoHome tent directly on the roof of your vehicle, but with some engineering, which I would assume Jeep did.
Mike, very cool concept truck, I'm glad that Jeep finally got around to it. They threatened to do it years ago. You could go round the world in that puppy.
