Both Kuat Sherpa and NV bike racks look great and tout the same robust type of construction. But after comparing the two Kuat hitch bike racks, I decided on the NV 2.0 mainly because it allows you to add on a 1-bike or 2-bike attachment in the future for a total 4 bikes. With the Sherpa 2.0, you are maxed out at 2 bikes with no option to add on. The NV also has a higher weight capacity and includes a built-in bike repair stand, which can be useful to have.
