good not great
I've used the rack in both the horizontal and vertical positions. It works well so long as it is tied back to the truck bed or bumper. I added an additional bolt through the intersection of the two pieces to help eliminate movement, as there is a fair amount of play at the receiver and the intersection of the pieces. Once the bolt was installed and it was tied off, it became a secure system. It's made of heavy stock and should last as long as the truck. I'd buy it again.
