Hi, I'm trying to decide if I want to add rails and crossbars to my "naked" 2019 Pilot roof, or just add the roof rack. Both of these are factory accessories; I'm not asking about after market parts. Just to be clear, the Honda roof rack looks like crossbars that mount directly to the grooves where the rails would go. The price for rails plus crossbars is $600-700 versus 300.00 for the "roof rack." Anybody installed just this roof rack? Picture attached is of the roof rack.
