1upUSA is the best hitch rack ever made. Worth the cost. Nearly ALL metal construction (no cheap faded plastic parts), can be added/removed from s vehicle in about 7 seconds, made in the USA, simple design etc. I actually made a YouTube video on how easy it is to take on and off a car or truck.

The only downside I see to the 1up is the lock offerings. To get matched key hitch and bike locks you have to order them together extra at $19 a piece. And the bike lock is just a wheel lock, so pretty worthless with quick release wheels. So you'd need to buy some kind of extra cable lock that would not be integrated. Not a huge deal, but something to consider and takes away some of the convenience factor.
