These are weights from Chevrolet.
They don't mention anything about the tandem set up, I'm sure because it was done someplace other than the factory.
I'd maybe add some weight to the racks if yours are solid, the picture that Chevrolet has shows spaces between the slats of the sides.
Hope this helps
