I installed a Thule Rack system for a Land Rover Range Rover roof basket system. First off I mounted the Thule 450 Crossroad roof rack system to the Range Rover roof rack siderails (be certain to choose the 58" crossbars length to sufficiently span across the Range Rover roof top). Then I attached the Thule 690 M.O.A.B roof basket to the Thule 450 Crossroad load bars. This is a superb universal cargo basket rack system for the Land Rover Range Rover. I also increased the cargo capacity of the basket by adding the 690 MOAB basket extension. I'd recommend also visiting this
list of Land Rover Range Rover rack setup photos or this
