I was really happy with service from Rack Attack initially, they were responsive to my specific questions and let me know which rack would fit my vehicle. I am really disappointed with this rack though. My vehicle meets the requirements stated in the specs, but it bangs against the road when we put 4 bikes on it (2 of them are for children under 7 and it still sways downwards way too far). Its not driveable in the 4-rack configuration, so we are only able to use it for 2 bikes (not very helpful for our family of 4). I tried to reach out to discuss possible exchange with Rack Attack but didn't get a response.
