To follow up my last post, attached are more photos of my setups.
I have RTT Ikamper mini, but did not have it in these photos. Probably in future

You may notice my ARB awning installed a bit further out from OEM roof rack because RTT edge will sit right above it (Ikamper RTT is 55” wide…wider than roofrack width). The 2 Rhino heavy duty cross bars which laid on top of cross bars of roofrack to give me 1.5” raise for easy install and take off RTT. Also they are the base for ARB awning brackets connected.
Happy Holidays to all and happy Land Cruiser
