We bought the Parkway rack a few months ago for our two bikes that we keep at our winter place in Florida, but we liked it better than the rack (another brand) we have up north so we decided to order another Parkway model to use there.
The rack is well made, really easy to use and has convenient features. Yes, you can lower the rack with the bikes on it, but we can easily open and close the hatch on our SUV when the arms are retracted, which is really good.
I made small changes where I chose to use an M12 bolt on either side of the hitch receiver (just long enough to barely touch, end to end and without a shoulder) for a really snug fit with no wobble. I also did forego the upper bolt and washer on the upper arm and use a 5/16" pin with latch so you can extend or retract the arm without any wrenches and cuts the time to mount or remove the bikes.
Overall, this is a good rack and it can be found for a good price.
