Went to Front Runner Outfitters today and had the Telluride looked at.
Factory rails are held on by 3 bolts per rail. 1 in the front, middle, and rear.
They collected measurements and identified mounting feet that will work with the factory rails. They said it should be a few weeks before it will be available to purchase.
I'll also be working with them on a non-factory rail setup using the 3 mounting holes for those LX owners or those who want a stronger rack.
