The popup roof is taking up the majority of the roof but there is still some space left to fit a small roof rack above the cabin. I used Thule 952 (20cm high) feet with Thule 765 cross bars to mount a Rhino-Rack luggage rack. Thule 527 locks are on all cross bars but I wouldn’t recommend them. I ordered 4 pairs in 2 separate orders and all locks came with the same keys. That leads me to believe that Thule has only one or a limited set of keys for their product. Convenient for me but also for a potential thief. The Rhino-Rack is designed to be used lengthwise covering half a roof of a smaller car but it fits my Mitsubishi L300 perfectly sideways.
