As roomy as my 04 Armada may be, I need extra dry storage when I travel with my family. Called Thule and Yakima, two of the biggest companies I know that carry luggage carriers. Both companies said the engineer that put together the Armada should be shot. They said because of the factory rails, they do not recommend any box be mounted safely. Thule did want to sell new 50" bars with Tracker kit and foot pack that would allow their sidekick box to work but would look funny with its 12-14" overhang. Has anybody successfully mounted a hard roof carrier on their Armada? Any tips would be greatly appreciated! Thanks.
