When I was looking at this, I seem to recall that the tents cannot be placed directly onto the OEM luggage rack, even if you have the crossbars, which I have. It has been a while but I believe my solution was to weld up a customer roof rack and drop the tent on top of that. If you add an aftermarket rack on top of the luggage rack, then add the tent, it gets really tall, cant fit into garages and is really top heavy, which means tippy. I still havent pulled the trigger on building or a custom rack. Part of that is my reluctance to dive into the issues that usually come with the process...the poor mounting system, potential for frozen or broken bolts/nuts, water leakage and the other challenges that I appear on this forum when pulling off the OEM rack.
