This set up worked out great! The Exposed Racks Crossbars for soft top is a great option for "topless" overlanding (I am aware of the risk of rain!). The rampage bikini top fits under the crossbars and provides enough protection from rain/sun. But what I love about this set up is the fact that the crossbars attach directly to the rollbars and gives the RTT a very solid platform (plus the weight of the tent distributes evenly across the body of the vehicle). They also have a "click-in" tent bracket option which offers a quick interlocking/ release system that makes the RTT installation and removal a lot easier (see the bracket photo below).
