Seeking information on compatibility of Tesla roof rack for 2019/20 Model S with glass roof with Thule Motion XT XL cargo box. I’ve purchased a new glass roof Model S that will be delivered in a week. I’m looking to purchase the Tesla roof rack. The Tesla photos show the rack arches some between its sides and center. The Thule Motion series cargo boxes are mostly flat over where it would sit on the rack. I’m concerned the cargo box will high center on the rack preventing its pincer type mounts from securely fastening to the rack. Has anyone had experience with this cargo box on the Tesla rack?
Of note: I cannot find the dimensions of the Tesla rack on its website. The Thule fit specs (thick book at REI) does not list any of its cargo boxes as being compatible with the 2019/20 glass roof Model S, including ones placed on a Thule rack. The REI sales rep called a Thule engineer who stated Thule does not recommend any cargo box over the glass roof due to risk to the glass. I do not understand this as Tesla states their rack can take 150# over the glass roof.
Any help on this would be most appreciated. Thanks.
