I have absolutely loved the 1 up heavy duty double paired with the Kuat Pivot. The back of my 4runner is where we all hang and drink beers after riding. I always have camp chairs in the trunk, swing the rack out of the way and 2 of us sit on the rear bumper. I also did the cupholder mod (

The only con I have is it adds like 10 inches to how far the rack sits away from the truck which just doesn't look as good as just the 1up stored vertical with no bikes on.
