Thanks. My GX does not have KDSS and the dealer still can't get a factory hitch. Lexus Nat'l won't let the dealer install a hitch mount, only the factory or port. Seems assinine Lexus would not provide for this, given the car is designed to tow! Why buy a V8 SUV if you can't tow with it.
My dealer has been helpful and is pointing me in the direction of an aftermarket hitch - I think it was the drawtite one, but I am not 100% sure. I will let you know how it goes once I get it installed.
