We are in the process of acquiring a 2012 Jeep Wrangler Unlimited (this is a 4-door of course), with the standard 1-piece removable Jeep hard roof.
Q: what have Wrangler Unlimited owners been deploying as a roof racking system capable of supporting a side-mounted awning, and a roof-top tent system?
*Our roof criteria are: the roof-top tent has to be detachable for winter storage leaving the roof rack "up there"; the rack must be able to support 2 adults (in the 170-LB range @) + roof-top tent system; the roof racking must be proven in the field by user/users here on the Forum; the most important: the racking must be rust resistant (say, aluminum) and be ingeniously engineered to allow fast/easy 1 or 2 person mounting (hopefully, without the need to remove/remount the 1-piece Jeep roof, after rack bolt-on!).
Some years ago, we had met South African Jack Stuhler in Utah and camped with him. he had a spectacular roof racking system aboard his FJ75 Toyota expedition vehicle (however, this was designed only for the FJ75). The whole system was ingenious, however again, designed for the Toyota.
