RTwrote a review of Kuat Sherpa 2 Bike Rack on November 22, 2014
When our old thule racks no longer worked with our new Subaru (with integrated roof racks) - we decided to switch to a hitch mount rack - this also helped with the fact that my short stature precluded me from loading bikes on my own. We have been very happy with the transition to hitch mount rack and more specifically the Kuat Sherpa - this rack is so easy to use - no more taking off wheels and having to make room for a dirty tire in your trunk. If you have a mountain bike with a thru axle (like my husband) this rack is also ideal because you don't have to deal with needing an adapter for a fork mount roof rack (which is what we had before).
And, no more having to wait for someone taller to help load my bike.
Also, Gun Metal Grey looks sweet with the orange accents!
Couple of things to keep in mind - First, if you have somewhat recessed hitch it is not ideal because you can't insert the hitch fully.
Second, if you park in a garage keep in mind that you will need about a foot of additional length to fit the car with the rack on (when folded)
