Unfortunately, only in the states that I know of. I have a few friends who bought them, and shipped to Montana Shipping.
This is the NV, which is what I'd get because you can get an add on to make it a 4 bike rack. It has a built in work stand. made of aluminum so it's lighter. Has an adjustment so it doesn't shake in the hitch.

They have a cheaper version, called the sherpa, which is only for 2 bikes.
