A suggestion for those with bumper-mounted hitches - since you can't see what is going on as you are driving ... how about finding a rough road or bit of highway and have a friend follow with a camera to capture movement so you can confirm everything is secure and tied-down.
I ask only because not long ago we followed a TT with a bumper-mounted hitch holding 4 bikes (2 adult, 2 kid) after they pulled-out of the Camping World in San Martin and headed north on US-101. The right lane is VERY rough and the bouncing made it look like all the bikes would either scrape the road and/or be launched off the rack when hitting the next pothole. We were towing and it so concerned us that we passed as soon as we could - wished I videoed it first though!
