When I ordered my R1T 10/12/20, I configured it with roof bars for my bikes. I later added the Yakama tent option and it removed my roof bars. I wanted both the set that came with the tent AND a set for the roof for the bikes. I contacted customer support via the chat as was mentioned above. Upon doing so, I was told they are totally interchangeable, but that they were so tight on inventory, they were limiting customers to 1 set initially and since the tent comes with a set, the others were removed by the configurator. When I stated that I wanted both, Emily told me that was the current limit, but maybe closer to delivery, or after the fact I could add them.
