This is a high quality bike rack, and the quality really shows! Setup is very easy and quick, and loading the bikes is a snap. Mechanically, its engineered very well, with all fastenings having vibration resistance nuts, so it won't fall apart when on an elongated trip or over time. One caveat relates to the trailer hitch pin hole on the Toyota Highlander which is much further back than regularly found on other vehicles, and the hitch pin hole on the Saris rack is only 1 1/2" from the end of the rack hitch mount. So the rack sticks half way out of the trailer hitch. It fits OK in the hitch receiver, but i'm not comfortable that its not going to wear long term. So, I'll probably have to figure something out (slight modification perhaps). Saris could easily solve this problem by having an extra hole drilled deeper into the hitch fitting (say 4" from the end). Whats really good is the hitch fitting itself. Saris supplies a threaded pin and built-in lock nut with padlock locking. This means the rack is padlocked to the car via the trailer hitch and the threaded nut/bolt means the whole thing doesn't rattle in its mount, a nice touch.
