This is the first and only hitch rack I've had on my 4Runner, and there are definitely plenty of reasons to like it. It was a cinch to setup, it's always been stable, it leans away from the vehicle with ease, and it was relatively cheap for a 4-bike rack. That said, I'm not totally happy with the carrying style. The cradles are fine, and can rotate as needed, but it can be difficult finagling certain frames, especially full suspensions, onto the rack. Also, I know the carrier arm can't extend 12 feet off the back of the vehicle, but it'd be quite the feat to get 4 bikes on this rack. I've only carried three at once on this rack, and it wasn't easy getting them on and off. Overall, not a bad buy for the price, but it works best only carrying two bikes at a time.
